South Swim wants to block YOU. Our fabric is made of ultra-opaque microfibers that filter the sun's rays for a UPF of 50+.

Feel, look, and do good with your suit. UPF (Ultraviolet Protection Factor) is used to measure the effectiveness of sun blockers. Our UPF 50+ blocks 98% of UV radiation from both UVA (skin aging) and UVB (skin burning) rays, significantly reducing your chance of over-exposure and skin cancer.

Sun tip: if you can see light through a fabric, UV rays can get through too. Cover up consciously.

Happy hour! Take it easy midday—lounge in the shade, enjoy a tasty beverage, long lunch, or anything that suits your fancy. 10-4 is when the sun clocks its strongest rays.

Don’t be fooled by clouds or umbrellas. They reduce, but don't block.
