What Our Gearhead® Experts Are Saying:
"This long sleeve tee is a staple for desert trips, alpine hikes, and fishing days. It offers full coverage without feeling hot or restrictive, and it doesn’t stink even after multiple wears. Great balance of protection and comfort."
We trust the Outdoor Research Eclipse Sun Long Sleeve Tee. Made from a lightweight, stretchy blend of recycled polyester, this breathable layer delivers UPF 50+ sun protection while wicking away sweat and staying fresh with odor-fighting ActiveFresh technology. Its long sleeves provide full-arm coverage for high-exposure days on the trail or water, and the Dynamic Reach design ensures we never feel restricted when casting, paddling, or scrambling. From alpine meadows to desert miles, this tee is our first layer of defense against sun and sweat.
