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. 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.
