5040 Polyester Spandex Swimwear Fabric 250gsm — 15% Elastane | Semi-Matte | Chlorine Resistant | 63 Inch
How does it feel?
250gsm polyester spandex semi-matte swimwear fabric. You pick it up and you immediately know it's a heavyweight. Solid, substantial, built like it's meant to handle serious pool time. The semi-matte finish gives it a clean, understated look — not shiny, not dead flat, just professional. 15% elastane provides a strong four-way stretch that snaps right back with authority. 160cm wide, 2 yards per kilo. The low yield tells you everything — this fabric packs a lot of weight into every meter. This isn't fabric you float in. It's fabric you train in.
Is it tough? Does it last?
Polyester at this weight is a chlorine-fighting machine. It resists degradation from pool chemicals better than nylon, holds its color through hundreds of hours of exposure, and won't turn brittle or thin out over time. The spandex recovery is rock solid — this fabric won't bag out, sag, or lose its shape after repeated wear and washing. Completely opaque, no lining needed. For competitive swimwear and serious training suits that get worn hard and washed often, it goes the distance. Not the kind that quits after one season.
What can I make with it?
Competitive swimwear, serious training suits, high-intensity aquatic sportswear. One-pieces that need to stay fully opaque under the most demanding conditions. Racing suits that need to feel like a second skin. If someone is in the water several times a week and expects their suit to look and perform the same months later, this is it. For lighter training or casual swimwear, we have 150gsm and 200gsm options. For maximum coverage and compression, pair this with our 320gsm nylon option.
FAQ
1. 250gsm — where does this sit in your swimwear range?
Heavyweight. We have lighter options at 135gsm, 150gsm, and 200gsm for regular training and resort wear. This 250gsm version is a significant step up — more compression, more durability, more structure. If the lighter options are like a regular swimsuit, this one is like a professional-grade tool for the water.
2. Polyester vs nylon for swimwear — why pick this one?
Chlorine resistance. Polyester naturally handles chlorine better than nylon. If your customer is a regular lap swimmer or training in a chlorinated pool several times a week, polyester will hold its color and structure longer than nylon. Nylon is softer and has a natural sheen. Polyester is the workhorse — drier, crispier, and built to last longer in harsh pool conditions. Pick polyester for maximum durability, nylon for maximum softness.
3. How's the stretch compared to your nylon swimwear fabrics?
Similar stretch performance. At 15% elastane, both this polyester version and our nylon swimwear fabrics deliver strong four-way stretch. The difference is in the hand feel — polyester feels drier and crispier, nylon feels softer and smoother. The stretch and recovery are comparable.
4. Is this fully opaque? Do I need a lining?
Yes, fully opaque at 250gsm. No lining needed. You can use it for one-pieces and training suits with complete confidence, even in lighter colors. This is one of the heaviest swimwear fabrics available, so transparency is never a concern.
5. How does this compare to your 200gsm polyester swimwear fabric?
Weight and compression. The 200gsm is solid for regular training, fully opaque with good stretch. This 250gsm version is heavier — more compression, more structure, built for even more demanding use. If the 200gsm is a reliable training partner, the 250gsm is for when you need that extra level of support and durability.
6. Can this be used for competitive racing suits?
Yes. The 250gsm weight provides the compression and muscle support that competitive swimmers look for, while the polyester construction ensures it holds up through countless hours of training. The semi-matte finish looks professional and sharp on the blocks and in the water.
7. Is this fabric suitable for medical or healthcare applications?
No. Our fabrics are designed and produced for swimwear, sportswear, and related uses. We do not currently manufacture or supply fabrics for medical, filtration, or industrial applications. If you need medical-grade textiles, we recommend consulting a specialist supplier.
