A versatile and technical midlayer designed to insulate and breathe during cold, high-output days up in the mountains, out on the slopes or along the trails, the Descender Long Sleeve Zip Hood is ready for any chilly, active adventure. Made with cozy yet technical brushed midweight fleece, the Descender features our corespun fibers—which uses nylon fibers wrapped in merino wool for added durability and quicker drying that retains next-to-skin softness. The fabric also features heat-trapping channels to help regulate your temperature during technical high-exertion pursuits like skiing, climbing or running in cold conditions. Lighter-weight side panels help manage moisture and dump excess heat when you’re moving fast, and the zippered hand pockets stash small essentials. Forward set side seams and offset shoulder seams improve comfort while wearing a pack, and we also added fold-over cuffs for a cozy touch.
