Whether in search of a cold weather camp jacket or a simple, yet reliable belay piece the warmth provided by box construction is a must! Normally used in the production of sleeping bags, this method minimizes heat loss from seam lines. The Frost Line Parka makes an exceptional insulating layer for those that prefer the solitude and challenge of winter activity at altitude. A helmet compatible, zip-off hood, adjustable alpine cuffs, and hem draw cord allow you to fine tune the fit. Slightly over-sized with a longer torso this “all mountain” parka is cut for layering and appropriate from late fall to early spring.
