Icebreaker Size Chart 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 Half Zip is ready for any active adventure. Made with high-loft textured fleece, the Descender features corespun fibers-which use nylon fibers wrapped in merino wool for added durability and quicker drying-as well as 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 back pocket stashes small essentials. Forward set side seams and offset shoulder seams improve comfort while wearing a pack, and thumbhole cuffs add a cozy touch.
