Designed as a technical insulator for ice climbing mountaineering and backcountry skiing the windproof Zip-in compatible Redpoint Jacket is a fast-drying synthetic alternative to down-insulated middle layers. Beneath the lightweight and breathable Keeler nylon ripstop shell is Primaloft® synthetic insulation a patented ultra-fine microfiber that absorbs three times less water than similar technical insulators. It's an ideal solution for anyone looking for a synthetic insulated jacket with a warmth-to-weight ratio similar to the high-fill down found in high-priced alpine jackets. The Redpoint compresses down into compact dimensions for easy packing. Elastic bound flex cuffs help seal in thermal warmth without sliding down your wrist on prolonged reaches.
