The men's Shifter Long Sleeve Zip Hood is Icebreaker's go-to hoody for everything from backpacking adventures to cool weather climbing trips. This hoody derives its comfort and warmth from its unbrushed terry merino fabric featuring corespun fibers and a touch of Lycra for stretch. Corespun fibers are nylon threads wrapped in merino wool, offering the ultimate combination of durability and next-to-skin softness. The Shifter also features a drawcord adjustable hood. Its reverse coil front zipper is backed by a stormflap and a chafe blocking chin guard.
