What to look for
- Fabric. 100% polyester or PBT lasts longest in chlorine.
- Support. A compressive racerback beats underwire for laps.
- Fit. Snug so it won't shift on push-off.

FAQ
Does chlorine-resistant fabric last longer?
Yes. Polyester and PBT keep their shape and color far longer than nylon or elastane.
