320gsm Nylon Spandex Lustrous Swimwear Fabric — Heavyweight Performance Knit | 59"

320gsm nylon spandex swimwear fabric. This is the heaviest one we carry. You pick it up and you feel the weight straight away — solid, substantial, not messing around. Lustrous finish, so it has a bright clean sheen, not matte. 160cm wide, 59 inches. Four-way stretch with real power behind it. Pull it and it snaps back like it means it.

Built for the pool. This weight of swim fabric can take serious wear — chlorine, saltwater, repeated washes, stretched over and over. Won't sag, won't bag, won't fade. Completely opaque, no lining needed. Nylon holds its color better than polyester in the water, and the spandex recovery stays solid through season after season. If you're making competitive swimwear or training gear, this is the one that keeps its shape long after the cheaper stuff gives up.

Competitive swimwear, serious training suits, performance pieces. If someone is in the water five days a week and needs their suit to look the same in December as it did in January, use this. Also works for high-end resort wear that needs to feel substantial and hold its silhouette. Not for lightweight draping or breezy cover-ups — this is for pieces that need to perform under pressure. For something lighter, we have 220gsm options in the same series.

1. At 320gsm, is this the heaviest swimwear fabric you carry?

This is the heaviest one we make. 320gsm — you feel the weight the moment you pick it up. It's substantial, completely opaque, and built to last. If you need a swim fabric that holds its shape through hundreds of hours in the water, this is it.

2. At this weight, won't it get heavy in the water or hold water?

No. Nylon doesn't absorb water, so the weight barely changes wet or dry. Heavy means solid, not waterlogged. And at this weight it's completely opaque — no lining needed. You get out of the pool and it won't cling wet and heavy to your body.

3. The lustrous finish — will it look greasy or too shiny in the water?

No. The lustre is in the nylon yarn itself, not a coating. It stays bright and clean in the water, not slick or oily-looking. A lot of competitive swimmers prefer this sheen — it looks sharp underwater, not dull. And it holds the lustre through dozens of washes. Won't fade to matte.

4. How's the stretch? Will it bag out?

Strong four-way stretch — pulls over 2x and snaps right back. The spandex content is dialed in properly, so recovery is solid. Normal wear, normal washing, won't sag. Use it for competitive suits and training gear, and a year later the snap is still there. Not the kind that quits after one season.

5. What's this fabric actually used for?

Competitive swimwear, serious training suits, performance pieces. If someone is in the water several times a week and needs their suit to look the same months later, this is the one. Also works for high-end resort wear that needs to feel substantial and hold its silhouette in and out of the water. Not for lightweight draping or breezy cover-ups — this is for pieces that need to perform.
