Outdoor Research Men's Eclipse Sun T-Shirt

The Eclipse Sun T-Shirt combines bluesign® approved fabric, UPF 50+ protection, and ActiveFresh™ odor control to deliver cool, quick-drying comfort for long, sun-filled days on the trail, at the crag, or in the backcountry.

Everyday Versatility, Trail-Ready Performance

The Eclipse Sun T-Shirt is built for life outdoors, whether you’re hiking or backpacking on sunbaked trails, working your favorite boulder problem, or loading up gear for your big weekend plans.

Engineered with lightweight, breathable fabric, this technical tee offers UPF 50+ sun protection and ActiveFresh™ odor control to keep you cool through extended activity. The quick-drying, moisture-wicking construction manages sweat, while the chafe-free design and dynamic reach patterning move naturally with you. A bonded neckline and straight hem enhance comfort, and a raised heat transfer logo finishes the look with subtle branding.
