Filled with the highest quality 850+ Loft RDS-certified ULTRA-DRY Goose Down™, protected by 3D NanoShell%trade; windproof and water-resistant fabric, 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 neck collar 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.
