"What Our Gearhead® Experts Are Saying:""I wore the Eclipse Sun Tank on a multi-day desert trip and it crushed it. It’s super soft, dries fast, and the UPF 50+ gave me confidence in full sun. Bonus—it doesn’t get funky after long days thanks to the ActiveFresh odor control.""When temps rise and the trail stretches on, we want a layer that keeps up without holding us back. The Outdoor Research Eclipse Sun Tank Top blends breathable performance with next-to-skin softness and powerful sun protection. It’s everything we need for hot summer hikes, long bike rides, and days outside from dawn to dusk. With UPF 50+ sun protection, quick-drying fabric, and ActiveFresh™ odor control, the Eclipse Sun Tank handles heat and sweat with ease. The bonded neckline and chafe-free design add comfort during movement, and the soft, bluesign®-approved fabric keeps things light, stretchy, and easy to wear—even deep into the mileage."
