The Dynafit Men's Chugach Windstopper Jacket puts a premium on breathability for rapid ski mountaineering objectives. When high winds demand you wear a shell during the ascent, pull the Chugach from your pack, zip it up, and open the two underarm vents for protection from the wind. The Chugach's Windstopper three layer shell prevents ripping alpine winds from penetrating your core, while the jacket's fully taped seams and DWR finish help to shed moisture from snow and ice. Lock the hood, cuffs, and hem down tight when the winds really start to pick up and pull through the crux in comfort thanks to the stretch softshell face. Reflective details help to keep you visible when the light is low when you start your summit bid, and multiple pockets on the inside and outside of jacket stow everything from topo maps to quick skintrack snacks.
