The Rap Men’s Ascent Jacket is a fully featured, water-resistant down jacket, using 650FP European Duck Down, designed for winter mountaineering and cold weather climbing use. The Ascent Jacket shares a similar feature set to the Neutrino Endurance, but features 650FP Hydrophobic Duck Down within a stitch-through baffle construction. We have been able to shed weight by using an updated, water-resistant Pertex® Endurance outer fabric, and light-weight YKK® zips throughout. A unique feature of the Ascent Jacket is the separate down-filled collar with a tricot fleeced lining, keeping your face protected from the elements and providing increased levels of warmth. Designed specifically for winter climbing, the Ascent Jacket also features a helmet-compatible hood, anti-snag Velcro adjustable cuffs and a stuff sack for increased packability.
