The high altitude sleeping bag

Filled with the highest quality 850+ Loft European Goose Down, protected by our patent pending 3D NanoShell™, the Alpine series is your cocoon in high altitude and arctic conditions.

Designed with a contoured mummy fit and anatomical shaped box foot, 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. The oversized zipper draft tube is fitted with the lightest and stiffest anti-snag material, for smooth operation. 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 more down is located in the top of the bag for maximum insulation. The soft touch lining fabric is down proof by construction and highly breathable offering a comfortable sleep.

The Alpine series is our choice for Karakoram expeditions, Alpine routes in the Andes, Himalayan high altitude climbing and winters in New Zealand.

Contoured Mummy
The Alpine contoured mummy shape is cut with a fitted hood, broad shoulders and large chest, to accommodate layering of clothing in extreme conditions. Generous room around the knees provides comfort when turning in this bag at night. An oversized foot box affords space for a pair of boot liners to be worn.
