Before a clothing brand places a large fabric order, it needs to know exactly what the material will look and feel like. This is where a fabric swatch becomes useful. A fabric swatch is a small sample of fabric provided by a textile supplier or manufacturer. It allows designers, clothing brands and garment manufacturers to evaluate the material before making a larger purchasing or production decision. For a new clothing brand, a swatch can be a simple but important tool for reducing mistakes and making better fabric choices. What Is a Fabric Swatch? A fabric swatch is a small piece or sample of fabric that represents a larger fabric quality or production lot. A swatch can help a buyer evaluate: Colour Texture Hand feel Thickness Stretch Drape Surface appearance Construction Overall suitability Instead of judging a fabric only from photographs or descriptions, the buyer can physically examine the material. Why Do Clothing Brands Use Fabric Swatches? Fabric selection affects how the final garment looks, feels and performs. A fabric may look good in a photograph but feel completely different when handled. A swatch allows the brand to make a more informed decision before committing to a larger quantity. It can be especially useful during: Product development Collection planning Colour selection Supplier comparison Sample development Bulk purchasing 1. To Check the Fabric Colour Colour can appear differently on a screen, photograph or printed document. A physical swatch provides a better reference for evaluating the actual fabric colour. Brands can compare the swatch against: Colour references Other fabrics Garment designs Accessories Branding elements This is particularly useful when developing a coordinated clothing collection. 2. To Feel the Fabric One of the biggest advantages of a physical swatch is that you can touch it. You can evaluate whether the fabric feels: Soft Smooth Crisp Lightweight Structured Stretchy Textured Hand feel can be difficult to judge from a product photograph. 3. To Check the Surface A swatch lets you examine the actual fabric surface closely. You can look for: Smoothness Texture Knit structure Surface uniformity Visible imperfections This can help determine whether the fabric matches the intended garment style. 4. To Understand the Drape Drape describes how fabric naturally falls or hangs. Take the swatch and allow it to hang over your hand or a surface. You can observe whether it: Falls softly Holds its shape Looks structured Folds easily Creates a fluid silhouette This can help a designer decide whether the fabric is appropriate for the intended garment. 5. To Check Stretch For garments that require flexibility, a swatch can provide an initial indication of how the fabric behaves when stretched. You can observe: Amount of stretch Direction of stretch Ease of movement Recovery after stretching For a final production decision, appropriate testing may still be required. 6. To Compare Different Fabrics A brand may receive several swatches from different suppliers. Instead of evaluating each fabric separately, the samples can be placed side by side. For example: Supplier A vs Supplier B The brand can compare: Colour Hand feel Surface Drape Stretch Appearance This makes supplier and fabric selection more practical. 7. To Develop a Garment Sample Before producing a complete garment, the brand may use a fabric swatch to decide whether the material is suitable for sampling. For example, a brand developing a T-shirt may receive several polyester fabric options. The team can select the most suitable fabric before producing the complete garment. This can help reduce unnecessary sample development. 8. To Build a Fabric Library Brands and designers can keep swatches from different suppliers and fabric qualities in a fabric library. A fabric library may contain samples organized by: Fabric type Supplier Colour Application Season Price range Performance characteristics Over time, this becomes a useful reference for future collections. 9. To Plan a Collection Fabric swatches can also help designers create a consistent collection. For example, a brand may select: One fabric for T-shirts One fabric for hoodies One fabric for track pants One fabric for sportswear The swatches can be arranged together to see whether the materials work visually as a collection. 10. To Match Colours Across Products Suppose a brand wants several products to use a similar shade of navy. Swatches allow the team to compare the fabrics physically. Even when two materials are intended to have the same colour, differences in: Surface Construction Finish Fibre characteristics can affect how the colour appears. Physical comparison helps identify these differences before production. What Information Should Be Recorded With a Swatch? A swatch becomes much more useful when it is properly identified. A simple swatch record can include: Fabric name Supplier name Fibre composition GSM DIA or width Colour Construction Sample date Supplier reference Intended application This prevents confusion when multiple samples are being evaluated. Fabric Swatch vs Fabric Roll A swatch and a fabric roll serve different purposes. Fabric Swatch A small sample used for: Evaluation Comparison Colour selection Product development Fabric Roll A larger quantity used for: Production Bulk orders Garment manufacturing The swatch helps you decide whether the fabric is suitable before purchasing a larger quantity. What Should You Check Before Approving a Swatch? Before selecting a fabric, check: Appearance Does it look suitable for the garment? Hand Feel Does it feel appropriate? Colour Does the shade match your requirement? Construction Does the fabric structure suit the product? Stretch Does it provide the required flexibility? Drape Does it fall the way you want? Surface Is the texture consistent? Performance Does it meet the requirements of the intended application? For important or large-scale orders, additional testing may be appropriate. Why Swatches Are Important for Bulk Orders Ordering a large quantity without checking the material first can create unnecessary risk. A swatch gives the buyer an opportunity to evaluate the fabric before committing to a bulk order. For example: Swatch → Evaluation → Approval → Bulk Order This is generally safer than: Bulk Order → Discover Problem Can a Swatch Represent the Entire Bulk Order? A swatch is useful, but it should not automatically be treated as a guarantee that every future batch will be identical. For important orders, buyers should clarify: Whether the swatch represents current stock Whether the colour will be reproduced Whether the specifications will remain consistent Whether the bulk order will be checked against an approved reference For repeat orders, keeping an approved reference swatch can be useful for comparison. How New Clothing Brands Can Use Swatches For a new clothing brand, the process can be simple: Step 1 Collect fabric swatches from suitable suppliers. Step 2 Label each swatch with supplier and fabric information. Step 3 Compare colour, feel, texture and construction. Step 4 Select the most suitable fabric. Step 5 Create a garment sample. Step 6 Evaluate the finished garment. Step 7 Approve the fabric before bulk production. This approach can help reduce unnecessary mistakes during the early stages of a brand. Frequently Asked Questions What is a fabric swatch? A fabric swatch is a small piece of fabric used to evaluate a material before making a larger purchasing or production decision. Why are fabric swatches important? They allow buyers to physically evaluate colour, texture, hand feel, drape, stretch and other characteristics that may not be clear from photographs. Can I compare suppliers using swatches? Yes. Swatches from different suppliers can be compared side by side to evaluate the fabrics more objectively. Should I order a swatch before a bulk fabric order? For an unfamiliar fabric or supplier, obtaining and evaluating a sample before a large order can help reduce purchasing risk. What information should be written on a fabric swatch? Useful information includes fabric name, supplier, composition, GSM, DIA or width, colour, construction and sample date. Final Thoughts A fabric swatch may be small, but it can play an important role in fabric sourcing and product development. It gives clothing brands a physical reference for evaluating a material before committing to a larger order. The basic process is simple: Collect → Compare → Test → Approve → Order For new clothing brands especially, using fabric swatches can make fabric selection more organized and help connect the material chosen on paper with the actual garment you want to create.

When starting or growing a clothing business, one important decision is whether to buy fabric and produce garments yourself or buy finished garments directly from a manufacturer or supplier. Both approaches have advantages and disadvantages. The better option depends on your budget, production quantity, product requirements, customization needs and business experience. Understanding the difference can help clothing brands choose a sourcing model that fits their current stage. What Does Buying Fabric Mean? Buying fabric means purchasing textile material from a fabric supplier and then converting it into garments through cutting, stitching and finishing. The basic process is: Fabric → Pattern → Cutting → Stitching → Finishing → Finished Garment A clothing brand may purchase polyester, cotton, rayon, blends or other fabrics depending on the product. This approach gives the brand more control over the garment development process. What Does Buying Finished Garments Mean? Buying finished garments means purchasing ready-made or already manufactured clothing from a garment supplier. The process is simpler: Finished Garment → Branding → Packaging → Selling Depending on the supplier, the garment may be sold as: Ready-made apparel Blank apparel White label clothing Private label products The brand can then add its own labels, packaging or other customization where available. Fabric Buying vs Finished Garments The biggest difference is the level of control and production responsibility. Factor Buying Fabric Buying Finished Garments Production control Higher Lower Customization Higher Usually lower Starting complexity Higher Lower Product development More involved Faster Initial production work Higher Lower Flexibility High Depends on supplier Suitable for beginners More challenging Easier Product uniqueness Higher potential Usually lower Inventory management Fabric + production Finished products Time to market Usually longer Usually faster 1. Cost Cost is one of the first things businesses consider. Buying Fabric When buying fabric, the total cost can include: Fabric Dyeing or finishing, if required Cutting Stitching Trims Labels Printing Embroidery Packaging Transportation Production wastage The fabric price alone does not represent the final garment cost. Buying Finished Garments With finished garments, many production costs are already included in the product price. You may still have additional costs for: Branding Packaging Transportation Marketing Customization For a small business, finished garments can sometimes make budgeting simpler. 2. Customization If you want a highly customized product, buying fabric can provide greater control. You can potentially control: Fabric Colour GSM Construction Fit Pattern Garment details Printing Labels Finishing With finished garments, customization depends largely on what the supplier offers. 3. Product Uniqueness Buying fabric and developing your own garments can help create more unique products. For example, a brand can develop its own: Fit Silhouette Colour combination Fabric selection Pocket design Collar Sleeve Garment details Finished garments may be shared across multiple customers, depending on the supplier's business model. Therefore, custom production can provide stronger product differentiation. 4. Minimum Order Quantity MOQ can influence the decision significantly. Fabric Buying You may need to purchase a minimum quantity of fabric and then manufacture garments from it. Finished Garments The supplier may have an MOQ based on: Product Colour Size Customization Branding Always confirm the MOQ before planning your collection. A lower MOQ can be particularly useful when testing a new product. 5. Production Time Buying finished garments can generally simplify the process because the garment is already manufactured. With fabric buying, the production process may involve: Fabric Sourcing → Sampling → Pattern → Cutting → Stitching → Finishing → Inspection This can require more time. If speed is a priority, finished garments may be more convenient. 6. Quality Control Buying fabric and manufacturing your own garments gives you more opportunities to control quality throughout production. You can inspect: Fabric Cutting Stitching Measurements Printing Finishing Final garment With finished garments, you primarily inspect the final product. Therefore, if detailed quality control is important to your brand, fabric-based production can provide greater control. 7. Inventory Management The two approaches create different inventory requirements. Fabric-Based Production You may need to manage: Fabric inventory Trims Work-in-progress garments Finished garments Finished Garments You mainly manage: Finished products Sizes Colours SKUs For a small business with limited storage space, finished garments may be easier to manage. 8. Design Flexibility Fabric buying provides greater flexibility during garment development. You can decide: Garment pattern Fit Fabric Colour Construction Details Finished garment sourcing is more dependent on the supplier's existing collection. If you want to frequently develop completely new designs, custom garment production may be more suitable. 9. Skills and Production Knowledge Buying fabric and producing garments requires more knowledge of apparel production. You may need to understand: Fabric selection Patterns Garment measurements Cutting Stitching Production planning Quality control Buying finished garments requires less production knowledge because much of the manufacturing process has already been completed. This can make finished garments attractive to new entrepreneurs. 10. Risk Both approaches carry different types of risk. Fabric-Based Production Potential risks include: Fabric quality problems Production delays Cutting wastage Stitching problems Incorrect measurements Unsold inventory Finished Garments Potential risks include: Limited customization Supplier stock issues Inconsistent availability Less product differentiation Quality differences between batches The best approach is to reduce risk through sampling and careful supplier selection. When Should You Buy Fabric? Buying fabric can make sense when you: Want custom products Need specific fabric characteristics Want greater control over fit Have access to reliable garment manufacturing Plan to produce larger quantities Want stronger product differentiation Have experience managing production For established brands, fabric sourcing can provide greater control over the complete product. When Should You Buy Finished Garments? Finished garments can be suitable when you: Are starting a new clothing brand Have a limited budget Want to launch quickly Want to test customer demand Don't have your own production setup Want to reduce development complexity Prefer smaller initial collections It can be a practical way to test a business model before investing heavily in custom production. Example: Starting a T-Shirt Brand Imagine someone wants to start a T-shirt brand. Option 1: Buy Fabric They purchase fabric and arrange: Fabric → Pattern → Cutting → Stitching → Printing → Labels → Packaging This provides more control but requires more coordination. Option 2: Buy Finished T-Shirts They purchase suitable blank T-shirts and arrange: Finished T-Shirt → Branding → Packaging → Selling This is simpler and can allow the brand to reach the market faster. Neither option is automatically better. The right choice depends on the business. What About a Growing Brand? A brand does not have to use only one sourcing model. It can use different approaches at different stages. Stage 1 — Testing Start with finished or white-label garments. Stage 2 — Learning Understand customer preferences and identify best-selling products. Stage 3 — Customization Introduce custom colours, fits or garment details. Stage 4 — Product Development Move toward custom fabrics and original garment designs. This can reduce the risk of investing heavily in custom production before understanding the market. A Hybrid Approach Some clothing brands use a combination of both models. For example: Core Products:Buy finished garments or white-label products. Signature Products:Develop custom garments using sourced fabric. This approach can provide both: Faster product launches Unique products It can also allow a brand to test new ideas without developing every product from scratch. Questions to Ask Before Choosing Ask yourself: 1. What is my budget? If the starting budget is limited, a simpler sourcing model may be preferable. 2. How unique does my product need to be? If uniqueness is critical, custom production may be more appropriate. 3. How quickly do I need to launch? Finished garments can simplify the launch process. 4. How much control do I need? The more control you need over fabric and construction, the more useful custom production can be. 5. How much production knowledge do I have? If you are new to garment manufacturing, finished products may be easier initially. 6. What quantity do I need? Your expected order volume can influence which production model makes financial sense. A Simple Decision Guide Choose Fabric Buying If: You want → More control + Custom products + Greater flexibility Choose Finished Garments If: You want → Faster launch + Lower complexity + Easier testing Choose Both If: You want → Fast-selling core products + Unique signature products Frequently Asked Questions Is buying fabric cheaper than buying finished garments? Not necessarily. The fabric price is only one part of garment production. Cutting, stitching, finishing, labour, wastage and other costs must also be considered. Is buying finished garments better for beginners? It can be easier for beginners because much of the manufacturing process has already been completed. Can I customize finished garments? It depends on the supplier. Some suppliers offer labels, printing, embroidery, colour choices and other customization options. Which option gives better quality? Neither automatically guarantees better quality. Quality depends on the fabric, manufacturing process, supplier, specifications and quality control. Which option gives more control? Buying fabric and managing garment production generally provides more control over the final product. Can a clothing brand use both methods? Yes. A brand can use finished garments for some products and custom production for others. Final Thoughts There is no universal answer to fabric buying vs buying finished garments. The better option depends on your: Budget + Quantity + Customization + Production Capability + Timeline + Business Stage If you are a new clothing brand with limited resources, finished or white-label garments can provide a simpler way to test the market. If you already have production capabilities and want greater control over your products, buying fabric and developing your own garments can provide more flexibility. For many growing brands, the most practical approach may be to start simple, understand customer demand and gradually move toward more customized products as the business grows.

How to Choose Fabric for Lightweight Sports Jackets A lightweight sports jacket needs to balance comfort, weight, breathability, flexibility and durability. Although the jacket may look simple, fabric selection can significantly affect how it fits, moves and performs. For sportswear brands and garment manufacturers, choosing fabric should involve more than comparing GSM or price. The fabric needs to work with the jacket's construction, intended activity, climate and overall design. This guide explains the key factors to consider when choosing fabric for lightweight sports jackets, including GSM, fabric construction, drape, stretch, recovery, breathability, comfort, durability, colour, printing and production requirements. What Makes a Good Fabric for a Lightweight Sports Jacket? A lightweight sports jacket should provide protection and comfort without making the garment feel heavy or restrictive. Important characteristics include: Lightweight construction Comfortable hand feel Good breathability Suitable drape Flexibility Stretch and recovery where required Wind-resistant or tightly constructed surface when needed Durability Shape retention Colour consistency Printing compatibility Easy maintenance There is no single fabric that is ideal for every lightweight sports jacket. A jacket designed for outdoor running may require different characteristics from a casual athleisure jacket or a lightweight training jacket. 1. Start With the Purpose of the Jacket Before choosing the fabric, determine how the jacket will be used. Running Jackets May require: Lightweight construction Breathability Easy movement Low garment weight Comfortable drape Training Jackets Can benefit from: Flexibility Durability Breathability Suitable structure Comfortable movement Outdoor Sports Jackets May require: Lightweight construction Protection from light wind Suitable surface density Durability Easy layering Athleisure Jackets Can prioritize: Appearance Soft hand feel Drape Comfort Surface texture Everyday durability The intended use should therefore be decided before selecting the fabric. 2. Choose the Right GSM GSM means grams per square metre and indicates the weight of the fabric. For lightweight sports jackets, GSM can influence: Overall garment weight Drape Body Coverage Comfort Layering Appearance A lower GSM fabric can create a lighter and more flexible jacket. A medium-weight construction can provide more body and durability while still remaining suitable for lightweight outerwear. However, higher GSM does not automatically mean better fabric. Fabric construction, yarn, density and finishing also influence the final performance. The correct GSM is the one that creates the desired balance between weight, comfort, structure and performance. 3. Lightweight Fabric for Easy Movement One of the main advantages of a lightweight sports jacket is freedom of movement. A lighter construction can help create: Reduced garment weight Easier movement Comfortable layering Softer drape Less bulk This can be useful for running, training and everyday sportswear. However, extremely lightweight fabric should still be checked for durability, opacity and surface stability. 4. Fabric Construction Changes Jacket Performance Two fabrics with similar GSM can behave very differently. Construction can influence: Drape Surface texture Breathability Flexibility Density Hand feel Durability Shape For example, a smooth polyester construction may create a clean minimal jacket, while a textured construction can provide a more technical appearance. The fabric should therefore be evaluated based on its actual construction rather than GSM alone. 5. Drape Affects the Jacket Silhouette Drape describes how naturally fabric falls and hangs. A soft fabric can create: Relaxed folds Fluid movement Softer silhouette Comfortable appearance A more structured fabric can create: Defined shoulders Stronger body Cleaner silhouette More technical appearance For lightweight sports jackets, the correct drape depends on the desired design. A relaxed athleisure jacket may benefit from softer drape, while a performance jacket may require more structure. 6. Stretch and Freedom of Movement Sports jackets should allow the wearer to move comfortably. Movement may include: Running Stretching Reaching Bending Training Cycling Warming up Stretch can be useful when the jacket is fitted or designed for high movement. Stretch fabrics can provide additional flexibility around: Shoulders Arms Back Elbows However, not every lightweight sports jacket requires high stretch. The required stretch should match the garment's pattern and intended activity. 7. Stretch Recovery Helps Maintain Shape Stretch and recovery are different. Stretch describes how much the fabric can extend. Recovery describes how well the fabric returns toward its original shape after being stretched. Good recovery can help the jacket maintain its intended appearance after repeated movement. This is especially relevant around: Elbows Shoulders Sleeves Back Cuffs Test the fabric repeatedly rather than evaluating recovery after only one stretch. 8. Breathability Matters A sports jacket can become uncomfortable if it traps too much heat during physical activity. Breathability can be influenced by: Fabric construction GSM Density Surface structure Porosity Layering A lightweight fabric does not automatically guarantee good breathability. For active jackets, evaluate how the fabric performs during realistic movement and wearing conditions. 9. Comfort and Hand Feel A lightweight sports jacket may be worn directly over a T-shirt or another base layer. Therefore, hand feel remains important. When evaluating fabric, check: Softness Smoothness Flexibility Surface texture Weight Drape Skin comfort The same GSM can feel very different depending on the yarn, construction and finishing. Always evaluate the physical fabric sample before production. 10. Durability for Sports Jackets Sports jackets can experience repeated movement, friction and washing. The fabric should therefore be evaluated for: Abrasion Repeated stretching Washing Drying Surface wear Shape retention Check whether the fabric maintains: Colour Shape Surface appearance Hand feel Stretch recovery A fabric that looks excellent when new may behave differently after repeated use. 11. Surface Density and Protection Depending on the intended use, a lightweight sports jacket may need a more closely constructed surface. This can help provide a different level of: Wind resistance Coverage Structure Protection However, increasing fabric density can also affect: Breathability Weight Drape Flexibility The fabric should therefore be selected according to the actual requirements of the jacket. 12. Fabric for Warm-Weather Sports Jackets For warm-weather jackets, focus on: Lower garment weight Breathability Comfortable hand feel Easy movement Suitable drape Lightweight polyester constructions can be considered when the jacket is intended primarily as a light outer layer. For warmer climates, avoid selecting a fabric solely because it has a heavier or more substantial feel. The finished garment should remain comfortable during extended wear. 13. Fabric for Training Jackets Training jackets may require a balance between: Flexibility Durability Breathability Comfort Shape retention A moderate-weight polyester construction can be considered when a little more body is required without making the jacket excessively heavy. Stretch may also be useful when the jacket has a fitted athletic silhouette. 14. Printing and Branding Compatibility Sports jackets may include: Team graphics Brand graphics Numbers Sponsor designs Custom artwork Before production, test the fabric with the intended printing process. Check: Print clarity Colour appearance Print adhesion Surface smoothness Stretch behaviour Appearance after washing A fabric that performs well with a small print may behave differently when used for a larger design. Always test the actual printing process before bulk production. 15. Colour Consistency Sports jackets are often produced in team or brand colours. Colour consistency is therefore important. Check: Fabric shade Batch-to-batch consistency Colour under different lighting Colour after washing Print colour Surface appearance For large production orders, approve the actual fabric colour before bulk production. 16. DIA and Fabric Consumption DIA refers to the approximate diameter or width of tubular knitted fabric. For lightweight sports jackets, fabric width can influence: Pattern placement Fabric consumption Marker efficiency Cutting waste Production cost A jacket can contain large pattern pieces such as: Front panels Back panel Sleeves Hood Collar Cuffs Side panels The available fabric width should therefore be considered during garment development. 17. How to Compare Fabrics for Lightweight Sports Jackets Don't compare fabrics only by GSM or price. Use a broader checklist: Factor What to Check GSM Is the weight suitable? Construction Does it suit the jacket? Drape Does it create the desired silhouette? Stretch Is enough flexibility available? Recovery Does it return toward its original shape? Breathability Is airflow suitable? Hand feel Is it comfortable? Durability Can it withstand repeated use? Surface density Does it provide the required protection? Colour Is the shade consistent? Printing Is it suitable for branding? DIA Is the width suitable for production? Cost Does it fit the target price? This provides a more complete understanding of fabric suitability. 18. Test the Fabric Before Bulk Production Before ordering large quantities, make a complete lightweight sports jacket sample. Test the process: Fabric Selection → Pattern → Cutting → Stitching → Branding → Wearing → Washing → Final Inspection Check: GSM DIA Drape Hand feel Breathability Stretch Recovery Colour Surface appearance Shrinkage Durability Printing performance Finished garment appearance Most importantly, test the finished jacket during realistic movement. Try: Walking Running Stretching Arm movement Bending Layering This can reveal problems that are difficult to identify from a fabric swatch alone. Quick Fabric Selection Guide Sports Jacket Type Important Fabric Characteristics Running jacket Lightweight, breathable, flexible Training jacket Durable, comfortable, flexible Outdoor sports jacket Lightweight, protective, durable Warm-weather jacket Lightweight, breathable, soft Athleisure jacket Drape, comfort, appearance Team jacket Durability, colour consistency, branding Fitted sports jacket Stretch, recovery, flexibility Casual lightweight jacket Softness, drape, easy maintenance Frequently Asked Questions What is the best fabric for a lightweight sports jacket? There is no single best fabric for every sports jacket. The right option depends on GSM, construction, breathability, stretch, recovery, drape, durability and intended use. Is polyester suitable for lightweight sports jackets? Yes. Polyester can be developed in lightweight, breathable, stretch and structured constructions suitable for different sportswear applications. What GSM is best for a lightweight sports jacket? There is no universal GSM. The correct weight depends on the jacket design, climate, desired structure, breathability and intended activity. Should a sports jacket have stretch? Not necessarily. Stretch is useful when greater freedom of movement is required, particularly in fitted or performance-oriented jackets. Is lightweight fabric always more breathable? No. Breathability depends on fabric construction, density, GSM and surface structure, not weight alone. What should I test before buying sports jacket fabric? Check GSM, DIA, construction, drape, hand feel, breathability, stretch, recovery, durability, colour and printing compatibility. Most importantly, make a complete garment sample before bulk production. Final Thoughts Choosing fabric for a lightweight sports jacket should begin with the intended activity and garment design. Consider: GSM + Construction + Drape + Stretch + Recovery + Breathability + Comfort + Durability + Colour + Printing + DIA + Cost For running and warm-weather sports, lightweight and breathable constructions may be preferred. For training jackets, flexibility and durability can become more important. For fitted performance jackets, stretch and recovery can play a larger role. For athleisure styles, drape, hand feel and surface appearance may be the main considerations. The best fabric is therefore not necessarily the lightest, thickest, stretchiest or most expensive option. It is the fabric that creates the right balance of comfort, movement, appearance, durability and performance for the finished sports jacket. Before bulk production, always test the actual fabric and finished garment to confirm that the fabric performs as expected.
