Gormsson -20° is the ultimate sleeping bag for very cold conditions. It is a true classic built on well-tried technology like the snug fitting mummy shaped design and the off-set double box chamber construction, much like a brick wall, designed to keep you warm even under extreme conditions. It has a durable nylon shell and inside the bag the highly insulating Norguard S-PO 85 fibre filling is wrapped in a very soft nylon. Together with the integrated foot box and the new innovative 3D neck baffle with magnetic closure heat loss is minimized without compromising comfort – and the use of annoying Velcro is avoided.
Nortech Style | S-NY 30D ( Outer schell / Lining )
The S-NY 30D is a very strong 30 diener nylon with a thread count of 302 and a weight of 43 g/m². It has a very smooth surface construction an a protective DWR finishing fot optimal water resistance.
Norguard S-PO | 80 ( Filling )
Specially Nordisk developed synthetic fibre with soft touch and high loft providing extra warmth for a comfortable sleep. Norguard S-PO 80 is non-allergic and meets Öko-Tex Standard 100. Soft touch and low maintenance.
Offset Double Box
The two box wall layers, one on top of each other, have their baffle walls offset relative to each other, which creates an appearance similar to that of a brick wall. Often used in bags with a large amount of filling – typically for extreme conditions.
Offset Triple Box
Offset triple box is basically designed as the Offset Double Box wall construction, but with an extra layer. The third layer adds to the unique insulation by increasing the volume and the temperature level. Best suited for sleeping in extreme cold.
The most simple design for a sleeping bag is to use the stitched through construction. Using this method the shell and lining are stitched together directly on top of each other to create the chambers into which the filling is inserted.
