A nod to the original Flylow pant design—the durable, ventilating Carhartt-style pants they built their company on—these hardshell pants blend technical fabrics with big-mountain style.

Flylow started to overcome the reality that mountaineering pants are not suited for moving down mountains at high speeds and ski and snowboarding pants are not designed for climbing mountains. The Chemical Pant represents the fourth generation of FlyLow innovation in pant technology. We took our burly articulated knees and cross-flow venting and combined them with Intuitive Fabrics™ 100% Dobby nylon 3-layer materials—custom made for this pant—to decrease weight for climbing and increase durability for ripping down steeps. All that, and it also features a comfortable fit and progressive style.
