2011 Version - The Montbell UL Spiral Down Hugger #0 is an incredibly lightweight and warm zero degree sleeping bag.
High quality 800 fill goose down, ultralight 12-denier Ballistic Airlight Nylon, Spiral Stretch™ System and elite 100-wash rated DWR are combined into this award winning bag.
With Montbell's patent pending Spiral Stretch™ System you get a closer fit which means one thing: a warmer more efficient bag. This system consists of elastic sewn into the baffles on the inside of the bag. This system allows the shell of the bag to keep its full shape while drawing the interior closer to you. The elastic baffles also allow the bag to stretch a little as you move and change positions.
An adjustable face hole in the tunnel hood improves warmth around your head. A shoulder collar prevents warm air from escaping through the top of the bag. The double draft tube prevents air circulation through the zipper area. Near full length side zipper allows flexibility for ventilation and comfort.
Ballistic Airlight™ - 12-denier Ballistic Airlight™ nylon is astoundingly thin, weighing less than half of a 45-denier nylon of normal shells while offering similar strength. This strength comes from the manufacturing process where the nylon is repeatedly stretched to align the molecules, much like the tensilizing of steel, resulting in an extremely light weight, wind resistant, breathable and water resistant fabric.
Polkatex™ DWR - Elite best water repellant performance. Polkatex™ is so durable that even after 100 washings it still retains 90% of its original repellency. Unlike other water repellent treatments, Polkatex™ DWR will retain its ability to keep you dry wear after wear, and wash after wash. Cotton Storage bag included.
