Top 7 Fabrics Used in Custom Sportswear and Gym Wear in the USA
If you are building a fitness brand, outfitting a sports team, or placing a bulk order for custom sportswear in the USA, fabric is the single most important decision you will make and it is also the one most buyers get wrong.
The right fabric determines how your garment performs under pressure, how it looks after 50 washes, how comfortable your athletes feel in the heat of competition, and ultimately how much your customers trust your brand. A gym hoodie that pills after two months, a football uniform that loses its print by mid-season, or a soccer jersey that suffocates players in summer heat these are not design failures. They are fabric failures.
This guide breaks down the top 7 fabrics used in custom sportswear and gym wear manufacturing across the USA what each fabric does, where it excels, and which products it is best suited for so you can make the right call before your bulk order goes into production.
Why Fabric Choice Matters More Than You Think
When buyers compare custom sportswear manufacturers, they often focus entirely on price per piece, MOQ, and lead time. Fabric is an afterthought until the order arrives and the product disappoints.
Here is what fabric directly impacts:
- Performance: Moisture management, breathability, and stretch affect how an athlete performs and feels during training or competition
- Durability: The wrong fabric degrades after repeated washing, losing shape, color, and structural integrity
- Print Quality: Sublimation printing, screen printing, and embroidery all behave differently on different fabrics
- Brand Perception: Customers feel fabric quality immediately. A premium fabric communicates a premium brand before a single logo is seen
- Cost per Wear: A slightly more expensive fabric that lasts three seasons is far cheaper than a budget fabric replaced every six months
Understanding fabric is not just a manufacturing detail it is a brand strategy decision.
Fabric 1: 100% Polyester The Industry Standard for Performance Sportswear
Best for: Custom soccer uniforms, custom American football uniforms, basketball jerseys, running gear, cycling kits
Polyester is the backbone of the global sportswear industry and for good reason. It is lightweight, durable, moisture wicking, and holds color exceptionally well across repeated washing cycles. For a custom sportswear manufacturer serving US sports teams and brands, polyester is the default fabric for performance-focused products.
Key Properties:
- Moisture-wicking: Pulls sweat away from the body and transfers it to the fabric surface for faster evaporation
- Lightweight: Does not add unnecessary weight during athletic movement
- Colorfast: Holds dye especially sublimation dye with exceptional vibrancy across years of use
- Quick-dry: Returns to a dry state significantly faster than cotton after intense activity
- Wrinkle-resistant: Maintains a sharp, professional appearance on and off the field
Why It Works for Custom American Football Uniforms and Custom Soccer Uniforms:
For custom American football uniforms and custom soccer uniforms, 100% polyester mesh is the top choice used by manufacturers across the USA. The open mesh weave maximizes airflow across the body during high-intensity play, and the fabric’s compatibility with sublimation printing means your team’s colors, numbers, and logos stay sharp from week one of the season through the final playoff game.
GSM Recommendation:
- Jerseys and lightweight tops: 120–150 GSM
- Shorts and base layers: 130–160 GSM
Fabric 2: Polyester-Spandex Blend The Performance and Flexibility Champion
Best for: Gym t-shirts, gym leggings, compression wear, yoga wear, custom gym jackets (fitted cut), activewear sets
A polyester-spandex blend typically 85% polyester / 15% spandex or 90% polyester / 10% spandex combines the performance benefits of polyester with the stretch and recovery properties of spandex (also known as elastane or Lycra). This is the fabric that defines modern activewear.
Key Properties:
- 4-way stretch: Moves in every direction with the body, eliminating restriction during squats, lunges, overhead movements, and dynamic athletic actions
- Compression support: At higher spandex percentages (15–20%), the fabric provides muscle compression that reduces fatigue and supports recovery
- Shape retention: Returns to its original shape after stretching no bagging at the knees or elbows after repeated wear
- Moisture management: Wicks sweat efficiently, keeping the wearer dry and comfortable during extended workouts
- Body-contouring fit: Sits close to the body without feeling restrictive the defining characteristic of premium activewear
Why It Works for Gym T-Shirts and Gym Wear:
For gym t-shirts and fitted activewear, polyester-spandex is the premium standard. It is the fabric behind the high performance gym wear that serious athletes and fitness brand customers expect comfortable during a warm-up, supportive during a heavy lift, and still looking sharp after the session ends.
GSM Recommendation:
- Gym t-shirts and fitted tops: 150–180 GSM
- Leggings and compression wear: 200–240 GSM
Fabric 3: Cotton The Comfort Standard for Casual Gym Wear
Best for: Gym t-shirts (casual/lifestyle), gym hoodies, gym sweatpants, streetwear-influenced gym wear
Cotton is the oldest and most universally understood fabric in apparel and in gym wear, it occupies an important niche. While it is not the top performer for high-intensity athletic activity (it absorbs moisture rather than wicking it), cotton delivers unmatched softness, comfort, and a natural feel that many gym-goers prefer for casual training, rest day wear, and lifestyle-focused gym wear products.
Key Properties:
- Softness: Unmatched natural comfort against the skin a key reason gym hoodies and casual gym t-shirts in cotton command premium retail prices
- Breathability: Natural fiber construction allows air to circulate freely
- Hypoallergenic: Gentle on sensitive skin no synthetic irritation
- Printability: Takes screen printing, DTG (direct-to-garment) printing, and embroidery exceptionally well
- Consumer Appeal: Carries a natural, sustainable connotation that resonates with a growing segment of US fitness consumers
Why It Works for Gym Hoodies and Casual Gym Wear:
Gym hoodies are one of the highest-demand products in the US gymwear market and cotton or cotton-blend hoodies dominate the lifestyle and streetwear-influenced segment. A heavyweight cotton hoodie (380–450 GSM) with custom embroidery or screen printing is a premium product that gym-goers wear from the weight room to the street, dramatically extending the product’s brand visibility beyond the gym floor.
GSM Recommendation:
- Casual gym t-shirts: 160–200 GSM
- Gym hoodies and sweatshirts: 380–450 GSM (heavyweight for premium feel)
- Gym sweatpants: 300–380 GSM
Fabric 4: French Terry The Ideal Fabric for Custom Gym Jackets and Hoodies
Best for: Custom gym jackets, gym hoodies, warm-up jackets, athleisure tops
French Terry is a mid-weight knit fabric with a smooth face and looped texture on the reverse side. It sits between lightweight jersey and heavyweight fleece making it the ideal fabric for custom gym jackets and hoodies that need to transition between a warm-up, a workout, and a post-gym coffee stop.
Key Properties:
- Mid-weight warmth: Light enough for active wear, warm enough for pre- and post-workout layering
- Moisture absorption: The looped interior absorbs light moisture without feeling damp or heavy
- Structure: Holds its shape well across repeated wear and washing hoodies and jackets in French Terry look fresh and structured even after months of regular use
- Drape: Falls and moves naturally on the body, giving gym jackets and hoodies a premium, clean silhouette
- Versatility: Works equally well for athletic settings and casual, everyday wear
Why It Works for Custom Gym Jackets:
For brands manufacturing custom gym jackets in the USA, French Terry is the fabric that bridges performance and lifestyle. It is soft enough to feel premium, structured enough to look sharp, and functional enough to justify wearing from the gym to daily life a key driver of the “athleisure” trend that continues to dominate US fitness apparel in 2026.
GSM Recommendation:
- Custom gym jackets and warm-up tops: 280–350 GSM
- Gym hoodies in French Terry: 300–380 GSM
Fabric 5: Fleece The Warmth Fabric for Cold Weather Gym Wear and Sportswear
Best for: Gym hoodies, gym sweatpants, sideline jackets, winter training gear, custom gym jackets for cold climates
Fleece is a synthetic knit fabric typically made from polyester with a brushed, fluffy interior that traps body heat for exceptional warmth. In the US sportswear market, fleece is the dominant fabric for cold-weather training gear, sideline jackets, and heavyweight gym hoodies designed for outdoor or cold-climate use.
Key Properties:
- Warmth-to-weight ratio: Delivers significant warmth without the heavy, bulky feel of wool or thick cotton
- Moisture-wicking: Polyester fleece wicks moisture away from the body unlike cotton, it does not feel damp and heavy when wet
- Quick-dry: Dries rapidly after training, making it practical for active use in unpredictable weather
- Durability: Maintains its structure and loft across hundreds of wash cycles
- Printability: Takes embroidery and screen printing well ideal for team logos and brand wordmarks on gym hoodies and sideline jackets
Types of Fleece for Sportswear:
- Standard Polar Fleece: Classic warmth for cold-weather training most common in team sideline jackets and winter hoodies
- Micro Fleece: Thinner and lighter, works well as a mid-layer in performance jacket systems
- Anti-Pilling Fleece: A premium variant that resists the surface pilling that makes cheap fleece look worn quickly
GSM Recommendation:
- Lightweight fleece midlayers: 200–280 GSM
- Standard gym hoodies and jackets: 280–380 GSM
- Heavy winter training fleece: 380–450 GSM
Fabric 6: Nylon The Premium Performance Fabric for Outerwear and Activewear
Best for: Custom gym jackets (shell/outer layer), windbreakers, training pants, high-end activewear, custom American football sideline jackets
Nylon is a premium synthetic fabric that delivers exceptional strength, abrasion resistance, and weather protection in a lightweight package. In the US sportswear market, nylon is the go-to fabric for performance outerwear gym jackets designed to block wind and light rain, sideline jackets for football and soccer programs, and high-end activewear lines that compete in the premium segment.
Key Properties:
- Strength: Stronger per-fiber than polyester significantly more resistant to tearing, abrasion, and wear under repeated physical stress
- Weather resistance: Naturally water-repellent and wind-resistant, making it ideal for outdoor training and sideline wear
- Lightweight: Delivers performance protection without added weight critical for athletes who need full range of motion
- Smooth texture: The naturally smooth surface of nylon gives sportswear garments a sleek, premium appearance
- Color depth: Holds dye with exceptional richness nylon garments tend to look more vibrant than equivalent polyester pieces
Why It Works for Custom Gym Jackets and Sideline Outerwear:
For a custom gymwear manufacturer building a premium product line, nylon outerwear is the fabric that signals quality immediately. US buyers especially in the premium and professional segment recognize nylon’s quality cues, and brands that use nylon in their gym jackets and outerwear can command significantly higher retail price points.
GSM Recommendation:
- Lightweight windbreaker and shell jackets: 70–100 GSM (often with inner lining)
- Training pants and track pants: 120–180 GSM
Fabric 7: Recycled Polyester (rPET) The Sustainable Future of Custom Sportswear
Best for: Custom soccer uniforms, gym t-shirts, custom gym jackets, gym hoodies, custom sportswear for sustainability-focused brands and schools
Recycled polyester made from post-consumer plastic bottles (rPET) delivers performance characteristics virtually identical to virgin polyester while significantly reducing environmental impact. In the US sportswear market, rPET is rapidly becoming a mainstream option rather than a niche one driven by consumer demand, school sustainability mandates, and brand positioning in the competitive activewear market.
Key Properties:
- Performance parity: Moisture-wicking, lightweight, colorfast, and durable matching virgin polyester in all key performance categories
- Environmental credentials: Uses significantly less energy and water to produce than virgin polyester; reduces plastic waste from landfills and oceans
- Consumer appeal: A growing segment of US fitness consumers actively prefer brands with verified sustainability practices rPET gives you a credible, verifiable claim
- Certifications: rPET fabric can be certified under GRS (Global Recycled Standard) a meaningful credential for school programs, corporate buyers, and sustainability-conscious brands
- Brand differentiation: In a crowded US sportswear market, a sustainability story built on verified rPET fabric gives your brand a meaningful point of difference
Why It Works for Custom Sportswear and Gym Wear in the USA:
For custom soccer uniforms, gym t-shirts, and custom gym jackets targeting US schools, universities, and eco-conscious fitness brands, rPET fabric delivers the full performance spec your buyers expect with an additional layer of brand credibility that virgin polyester cannot offer. With the US sportswear market exceeding $90 billion in 2025 and sustainability becoming a key purchase driver, rPET is the fabric that future-proofs your product line.
GSM Recommendation:
- rPET jerseys and lightweight gym tops: 130–160 GSM
- rPET gym jackets and outerwear: 160–220 GSM

How to Choose the Right Fabric for Your Sportswear or Gym Wear Order
Use this decision framework before placing your bulk order:
If you are ordering custom American football uniforms or custom soccer uniforms: Go with 100% polyester mesh (120–150 GSM). It is the industry standard for a reason proven performance, colorfast printing, and durability across a full competitive season.
If you are ordering gym t-shirts for a fitness brand: Choose polyester-spandex blend (150–180 GSM) for a performance-focused product, or medium-weight cotton (160–200 GSM) for a lifestyle or casual training product. Many brands offer both to serve different customer needs.
If you are ordering gym hoodies: Heavyweight cotton or French Terry (380–450 GSM) for a premium lifestyle hoodie. Fleece (300–380 GSM) for a warm-weather training or cold-climate performance hoodie.
If you are ordering custom gym jackets: French Terry for a mid-weight athleisure jacket. Fleece for a warm training outer layer. Nylon for a premium performance or weather-resistant jacket. Match the fabric to the intended end use of the garment.
If you are building a sustainability-led brand: rPET polyester delivers the same performance as virgin polyester with a verifiable sustainability credential. Pair with GRS certification for maximum credibility with US school programs and eco-conscious retail buyers.
