An everyday jacket that's still tough enough for the backcountry. The Chockstone Jacket is lightweight, easy to pack and carry, and wind-resistant. It's made from a durable, extremely abrasion-resistant doubleweave fabric, so it can take some abuse. Micro-chamois lining on the chin guard eliminates chafing around the face and neck, adjustable hem for a custom fit. DWR finish repels water.
