What Our Gearhead® Experts Are Saying:“I’ve used this for surfing, paddling, and even pool days—it stays comfortable and secure, dries quickly, and offers great UV protection. A total summer essential.”Built for long days in and on the water, the Patagonia Men's RØ® Rashguard blends technical performance with thoughtful design. The recycled polyester and spandex jersey offers four-way stretch for fluid movement, while 40+ UPF sun protection shields skin from harsh rays. Flatlock seams and seamless underarms reduce chafing while paddling, and the boardshort connector keeps the fit locked in through every session. With Fair Trade Certified™ construction and a low-profile design, this top fits like a second skin so you can focus on the waves ahead.
