If you’re going surfing or taking part in any energetic water sports, a rash vest is essential. Worn next to your skin, they prevent painful chafing and rashes caused by the friction of a wetsuit or your board as you move around. 

A rash guard will prevent that painful rubbing and give an extra layer of insulation in cold water. Even more important is the protection they give you against the sun’s harmful UV rays. Sunscreen only lasts so long, even if it’s waterproof, and wearing a rash vest means you don’t have to worry about reapplying it if you’re in the water for a while. Look for a UPF 50+ rating for reassurance that the material will block 98% of the sun’s harmful rays. Here are the rash vests we recommend.
