Looking to carry less on multi-day alpine adventures? With its technical Atmos™ fabrics and high-loft insulation, the superlight Prosar Jacket is the mountaineer’s down jacket of choice.
Whether you’re planning a spring ski tour or travelling hut to hut, the versatile Prosar Jacket is warm and extremely packable. The lightweight 10D Atmos™ shell and lining allows the 800FP hydrophobic European goose down to loft fast, giving instant warmth with minimal weight. It also features zoned stitch-through construction for refined styling and bulk-free mobility during active mountain use. The tightly woven polyamide yarns of the Atmos™ fabric outer make it highly wind and water resistant and the jacket also includes a down-filled hood, low-profile elasticated cuffs, a pair of zipped hand pockets and a stuff sack for convenience on the move.
With a weight of just 371g, alongside zoned midi and nano baffles for improved down distribution, the Prosar Jacket provides excellent warmth and weather resistance for both alpine use and everyday insulation.
Atmos™ is our own wind and water-resistant fabric. Constructed from tightly woven nylon yarn, Atmos™ is a soft feel fabric that allows insulation to fully loft whilst remaining highly breathable. Lightweight and packable, Atmos™ is perfect for outdoor garments.
