Blaze on with the AirExchange UPF Collection. Whether you’re stepping out the door for a day hike, climbing session, or backcountry excursion, throwing on this go-to baselayer should be your first step. AirExchange performance fabric is breathable and quick-drying, keeping you in your comfort zone as you power forward. When the sun pops out and outer layers come off, UPF 50 protection keeps you safe from blazing rays. Dropped shoulders and abrasion-resistant seams keep you comfy, agile, and chafe-free under the weight of your pack or racking sling—even on days that start early and end late. Need to snag a snack or lip balm on the move? A hidden zip-secure pocket is easily accessible, even when you’re buckled into a harness or your backpack hip belt. Designed to be your trusted trail and alpine baselayer, this airy crewneck will also keep you cool and burn-free on sunny beach, boat, and bike days.
