UV Protection is a very serious matter at O'Neill! Every summer we design a special collection of UV protective clothing including men's UV shirts and rash guards that protect against the sun's harmful rays. All our Lycra UV tops feature top-of-the-line technology, like: U.P.F. 50+, 4-way stretch, rash protection, a boardshort connector and quick-drying fabric. Surf lighter and longer while protecting yourself from the sun.
