A well-tried and tested winter sleeping bag

The Gormsson -10° is the classic winter bag in the Nordisk collection. Over the years it has been updated and optimised to this modern version. It has a classic mummy construction offering a snug fit and optimal insulation thanks to the Norguard S-PO 85 fibre filling and the integrated foot box keeping your feet warm all night. The lining is a very soft 30 D nylon and the shell is also made of highly durable nylon. To avoid the use of annoying Velcro, the Gormsson features a new innovative 3D neck baffle with magnetic closure making it a both practical and very comfortable sleeping bag.
