Focus on swimwear
The anti-UV fabric we use in our anti-UV t-shirts and swimwear has a UPF (Ultraviolet Protection Factor) rating of over 50. These products provide an extremely good level of protection from the sun. Even when wet, the materials can block 98% of UVB and 95% of UVA rays. This avoids the use of sunscreen, which is very harmful to the oceans.
