Every custom athletic wear order starts with the same foundational decision: what fabric? Get it right and the garment performs, prints beautifully, and lasts. Get it wrong and even perfect artwork can’t save a jersey that soaks up sweat like a towel or a hoodie that pills after three washes.
Here’s how polyester and cotton — and the blends between them — actually compare for sportswear, from a manufacturer’s perspective.
Polyester: The Performance Standard
Strengths
- Moisture management: polyester is hydrophobic — it wicks sweat to the surface instead of absorbing it. This is the single biggest reason it’s the best fabric for sportswear worn during exertion.
- Durability: high abrasion resistance, excellent shape retention, resists stretching out
- Colorfastness: holds dye brilliantly; sublimation printing (the pro standard for team kits) only works on polyester
- Quick drying: a soaked polyester jersey dries in a fraction of cotton’s time
- Shrink resistance: virtually none — what you approve in sampling is what arrives in bulk
Weaknesses
- Odor retention: polyester’s oil-loving fibers hold onto body odor more than cotton — anti-odor finishes help and are worth specifying
- Hand feel: basic polyester can feel slick or plasticky; quality varies enormously with knit and finishing
- Static: more prone to static cling than natural fibers
- Heat sensitivity: melts rather than burns — relevant for industrial laundering, not normal use
Best for
Soccer jerseys, basketball uniforms, training tees, leggings, cycling kits — anything worn during sport. Our entire sublimation range is polyester-based because the fabric and the print method are a matched system.
Cotton: The Comfort Classic
Strengths
- Natural comfort: soft, breathable hand feel that customers love for casual wear
- Odor resistance: naturally less odor-retentive than polyester
- Print versatility: takes screen printing and embroidery beautifully; the vintage soft-hand print aesthetic lives here
- Perceived value: “100% cotton” still signals quality to many consumers
Weaknesses
- Absorbs moisture: cotton holds up to 7% of its weight in water — during sport, that means a heavy, clingy, slow-drying garment
- Shrinkage: expect 3–5% shrinkage unless pre-shrunk; your size specs must account for it
- Wrinkling and bagging: loses shape faster than polyester, especially in knees and elbows
- Color fading: dark cottons fade faster than polyester equivalents
- Can’t sublimate: dye sublimation doesn’t bond with cotton — full-color all-over designs are off the table
Best for
Fan tees, casual hoodies, supporter merchandise, and lifestyle pieces worn around sport rather than during it.
The Blends: Where Most Orders Land
Pure-fiber garments are the exception in custom manufacturing. Blends capture the best of both:
- Cotton-poly (CVC, 60/40): the classic tee blend — cotton comfort with poly’s durability and reduced shrinkage. Screen prints beautifully.
- Poly-cotton (50/50 or 65/35): performance-leaning; better moisture management than CVC while keeping a natural feel. The workhorse for training apparel.
- Tri-blends (poly/cotton/rayon): the premium fashion-athletic blend — ultra-soft drape, vintage look, heather effects. Higher cost, worth it for retail brands.
- Poly-elastane (88/12 to 75/25): the foundation of leggings, compression wear, and modern fitness apparel — four-way stretch with recovery.
- Cotton-poly fleece (80/20): the standard hoodie fabric — warm, soft, stable, prints and embroiders well.
Fabric Weight (GSM) Matters as Much as Fiber
Two “polyester jerseys” can feel completely different at different weights:
- 120–150 GSM: featherweight — singlets, lightweight training tops
- 150–180 GSM: the team-uniform sweet spot — soccer and basketball jerseys
- 180–220 GSM: substantial tees, polo shirts, mid-weight training wear
- 280–400 GSM: hoodie and sweatshirt fleece territory
Always confirm GSM in your quote — it’s the most abused spec in budget manufacturing, and a 140 GSM “jersey” sold as teamwear will feel like tissue.
Matching Fabric to Product: Quick Reference
- Match soccer/basketball jerseys: 100% polyester interlock or mesh, 150–180 GSM, sublimated
- Training tees: poly-cotton or tri-blend, 160–180 GSM
- Hoodies: 80/20 cotton-poly fleece, 300–350 GSM, screen print or embroidery
- Leggings: poly-elastane (or nylon-elastane), 220–280 GSM, four-way stretch
- Varsity jackets: wool/nylon body with leather or PU sleeves (see our varsity sourcing guide)
- Polo shirts: cotton-poly piqué, 180–220 GSM, embroidered crest
What to Ask Your Manufacturer About Fabric
- Exact composition and GSM — in writing, on the quote
- Whether fabric is knitted in-house or sourced (and from where)
- Shrinkage test results for cotton-containing fabrics
- Colorfastness ratings for your chosen colors
- Physical swatches before you approve bulk — non-negotiable

Get Fabric Advice on Your Actual Products
Fabric choice is product-specific — and small details matter. A training tee meant for humid climates might warrant a lighter 150 GSM mesh, while the same design for a winter training line could go to 200 GSM interlock. If your line mixes printed and solid garments, your factory should confirm that the dyed solids and sublimated prints come from compatible fabric bases so colors stay consistent across the collection. When in doubt, request swatches in two or three candidate fabrics and compare them side by side — hand feel, stretch, and opacity are impossible to judge from a spec sheet alone.
