The Bum in the Sun

☀️ The Bum in the Sun

Catch waves, not sunburn.

Whether you're paddling out at dawn, carving up the wake, or chasing warm tides all afternoon, The Bum in the Sun rash guard has your back (and shoulders, and chest). Engineered with ultra-soft, four-way stretch fabric, this long-sleeve performance sun shirt delivers built-in UPF 50+ sun protection so you can stay out in the water longer without worrying about harsh UV rays, wind, or board rash.

Designed with an ergonomic slim fit and a longer body cut, it stays securely in place while you move—no riding up, no chafing, just pure ocean freedom.
