Stop wearing bunched-up board shorts under your wetsuit! O'Neill's Thermo Shorts make a great base layer, under your wetsuit on cooler days or under your board shorts on warmer ones, and are designed especially for thermal layering. Made of the same great material as the O'Neill Thermo wetsuit tops, these shorts are excellent at wicking moisture away from your body, and their smooth flatlock stitching make sure you don't end up with weird uncomfortable marks on your skin at the end of a session.

The Thermo Shorts are constructed from an odor-resistant material, and feature grippy elastic around the waist and leg openings to keep everything in its place.

These shorts tend to run small. We recommend that you go one size up from normal.
