From multi-day backpacks and alpine trail runs to day hikes and weekend campouts with the fam—this is your new go-to sun hoody. AirExchange fabric is super breathable, quick-drying, and sweat-wicking with UPF 50 protection to keep your comfort in check and UV rays at bay when temps, pace, and vert are soaring sky-high. When the sun pops out on the trail, pop up your scuba hood and slip into the thumbholes for maximum coverage. Dropped shoulders and abrasion-resistant seams keep you comfy, agile, and chafe-free for long, sunny days under the weight of a pack or racking sling. The side-panel zippered pocket keeps lip balm or an energy gel within reach when you're buckled into a harness or hip belt—or your car key safe for a quick trail run. Designed to be your trusted trail and alpine baselayer, this airy hoody will also keep you cool and burn-free on sunny beach, boat, and bike days.
