Beach Proof Fabrics Suits made with our signature swim fabric offer UPF 50+ protection, and they can stand up to sand, sweat, and chlorine. Live wear tests have shown that even after 100+ hours of use in chlorinated water, the fabric retains its shape and compression power. To keep your suit looking its best, we recommend hand washing your suit by itself with cold water and a gentle soap. Do not soak, just a quick wash will do! Hang dry to keep your suit in tip top shape. This extends the lifetime of your suit by avoiding fiber degradation.
