Filled with the highest quality 850 Loft European Goose ULTRA-DRY DownTM, protected by our 3D NanoShellTM, the Alpine series is your cocoon in high altitude and arctic conditions. Designed with a contoured mummy fit and anatomical shaped foot box, warmth is trapped close to the body without a claustrophobic feel. With an oversized neckcollar and hood-seal, drafts are kept out, minimizing heat loss around the face.A security pocket located inside the bag is easily accessible, ideal for stowing electronics to preserve battery performance in extreme cold. Using a side block baffle construction to maintain a 60/40 fill ratio means that more down is located in the top of the bag for maximum insulation. Suggested use: Base camp; Winter backpacking; Snow camping; Ski touring; Alpine climbing; Expeditions
