Sun protective clothing can be a good addition or alternative to using sunscreens. Since sun protective clothing is an easy way to protect your skin from the sun without using chemicals such as those found in sunscreens, it is becoming more popular. This clothing is rated by a UPF (ultraviolet protection factor) rather than a SPF (sun protection factor), as it protects from both UVA and UVB rays. A garment with a UPF of 50 would block 98% of all UVA and UVB rays. Sun protective clothing can be found for men, women, and children, along with hats and sun protective swimwear.
