Blaze on with the AirExchange UPF Collection. From multi-day backpacks and alpine trail runs to weekend campouts with the fam, this is your new go-to sun hoody. AirExchange fabric is ultra-breathable, quick-drying, and sweat-wicking, with UPF 50 protection to keep your comfort in check and harmful UV rays at bay when temps, pace, or 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 during long, sunny days under the weight of a pack or racking sling. The side panel zippered pocket keeps car key, lip balm, or energy gels within reach—perfect for quick trail runs or when you're buckled into a harness or hip belt. Designed to be your trusted trail and alpine baselayer, this airy hoody also keeps you cool and burn-free on sunny beach, boat, and bike days.
