W Stretch Down Jacket
A first-of-its-kind down jacket built around seamless woven baffles and a stretchable outer fabric. Exceptionally warm for its weight, unusually comfortable for a down piece, and more weather-resistant than traditional constructions. Designed for alpine use, but you’ll reach for it every time the temperature drops.
Technical Specifications
Seamless versatility
The Stretch Down Concept introduced a breakthrough in down engineering: seamless I-tube baffles woven directly into the fabric and a two-way stretch outer that was previously nearly impossible in down garments. This double-wall construction removes cold spots, improves durability and weather resistance, and creates a level of comfort most down jackets never reach. Filled with premium 750 FP water-resistant down, it compresses easily and lofts quickly, balancing warmth, resilience, and everyday usability. Durable enough for daily wear, yet technical enough for demanding alpine environments."
