Hjalmar is the ideal sleeping bag if you don’t want to be sleeping in a tight cocoon. It allows your entire body to move during your sleep and can be converted into a blanket or zip two bags together to create a double bag. The all-round zipper allows you to adjust the heat and ventilation during the night to fit your exact needs. Hjalmar is available in a summer and a 3-season version depending on how much insulation you require. Both bags have an integrated zipper baffle which prevents the cold from escaping through the zipper.

Nortech Style: S-PO 50D (Lining)

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.
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.
