Built for high-altitude hiking, mountaineering, and snowsports, this lightweight jacket uses 850-fill water-resistant goose down with 90% down content and 1000+ cleanliness. A 10D TORAY nylon shell with a DWR finish helps shed light precipitation, while zoned baffles and anti-down stitching support even warmth. One-piece underarm patterning improves mobility. A stand collar, elastic cuffs, adjustable hem, YKK zippers, packable design, and four-pocket layout balance protection, movement, and efficient storage.
