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 new line of Chain Reaction tops, named after the classic 5.12c arete. Each piece 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.
