* If you're between sizes, size up — you'll want room to layer underneath on the trail.
* Actual fit may vary slightly by style, fabric stretch, and down/insulation loft.
Gain a leg up when you’re legging it out on the trail—even when the sun is beating down. Tough yet lightweight, these shorts combine the breathable, quick-dry comfort of AirExchange with UPF 40 sun protection for coverage from blazing rays. An encased elastic waistband with an internal drawcord helps you dial in the right fit, whether you’re tearing up trail or sending up routes. Angled, drop-in hand pockets allow for easy access when you’re wearing a pack or harness, while zip-secure back pockets keep your phone, keys, and wallet safe while you’re on the move. At the end of the day, use the hanger loop to air-dry your pants from your tent, trekking pole, or tree branch.
