Cool, stretchy climbing tank inspired by Smith Rock

Climbing at Smith Rock is world-class, but the climbers themselves come with less desirable side effects: Sweat, smells, and sunburns. Beat the desert heat (and its repercussions) with the Chain Reaction Tank, named after the classic 5.12c arete. It packs in UPF 50+ sun protection, ActiveFresh™ odor control technology, send-enhancing stretch, as well as a wicking and quick drying performance so you'll dry off just in time for the next go. Don't sweat the steep stuff, wear the Chain Reaction instead.
