Sea to Summit Alpine Ap II 5ºF Ultra-Dry Down Sleeping Bag

$699.00 - $729.00
Filled with the highest quality 850+ Loft European Goose Ultra-Dry Down™, protected by Sea to Summit's 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 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.

Following a successful 1984 climb up the north face of Mount Everest, one of the summiteers, Tim Macartney-Snape decided to return six years later so that he could do what no one else had done - climb it starting from sea level, that is from "sea to summit".

For this trip, in 1990, Tim swam in India's Bay of Bengal and then set off on foot across the Gangetic plain toward the distant Himalayan foothills and four months later, set foot once again on the highest point on earth. Tim's solo ascent of Mt. Everest was named the "Sea to Summit" expedition.

Back in Australia, he joined forces with friend Roland Tyson to build a business that could make use of their knowledge of the outdoors to create truly ingenious, well-made but affordable outdoor equipment. They named their company Sea to Summit® after Tim's expedition and the business prospered. Today the Sea to Summit brand continues to provide innovative gear and serves a growing band of outdoor enthusiasts all over the world.
