Up monstrous mountainsides molded by glaciers and across narrow wind-swept ridgelines on our way to the summit, the Mountain Equipment Arrow Hooded Jacket offers lightweight protection in unforgiving locales. Clocking in at under a pound, the Arrow aims to conquer mountaineering expeditions and ice-climbing escapades. The wind-resistant fabric and elastane hood keep us protected from icy blasts, and the stretch fabric offers full mobility to reach up and plant our axe into icy walls. The low-profile design seamlessly fits into a layering system so we can be prepared for changing conditions on our way to the summit.
