What Our Gearhead® Experts Are Saying:"This is the tee I grab for long summer hikes and travel days. The Eclipse Sun T-Shirt feels soft like a favorite casual shirt, but it performs like a tech layer—quick-drying, stretchy, and the odor control really holds up over time."When the sun is relentless and the trail keeps going, we pull on the Outdoor Research Eclipse Sun T-Shirt. It’s built for long, active days under big skies with soft, breathable fabric that stretches with us and offers serious sun protection. Whether we’re racking up miles on trail or relaxing at camp, it keeps us dry, cool, and feeling fresh.With UPF 50+ protection and odor-fighting ActiveFresh™ technology, this tee handles heat, sweat, and repeat wears with ease. Its chafe-free design and thoughtful details—like a bonded neckline and split side hem—add all-day comfort without overcomplicating things. It’s the everyday sun shirt we rely on when conditions demand more.
