Description
The FRONT 800 3D is a winter down sleeping bag with a unique design. It is a warm mummy-sleeping bag that can be transformed into a blanket, opened for ventilation at the feet, or attached to another sleeping bag.
The long zipper makes it easy to regulate the temperature inside, which increases comfort during winter hiking and mountaineering. In a mountain hut, it is handy to use it as a blanket. At the mountain foot, where it is usually warmer, it is possible to open the zipper at the bottom or top to release excess heat.
3D technology is based on a differential cut, where the outside of the sleeping bag is larger than the inside. The design ensures that tension is applied exclusively to the inner fabric of the sleeping bag, always leaving free space for the down insulation. This provides stable and uniform heat retention even during active sleeping movements.
Two insulated strips securely fix each other along the zipper and prevent cold air penetration.
Insulated with hydrophobic 800 FP goose down that stays dry and efficient even on long trips.

I’ve bought the 800 in green in the fall of 2024.
It has served me well in the high fjells of Norway in snow and windy conditions.
Absolutely trustworthy companion. I’ve come to Love the front zipper and ability to open it up as a blanket to cover multiple persons freezing inside a tent.
The small pocket inside keeps phone and powerbank warm during the night, but could be slightly larger in future iterations of the bag.
Exceptionally high build quality and solid rating.
As a male, warm sleeper, I’ve slept very comfortable in -10 C with just a small hat and short underwear.
I bought another sleeping bags (450), and it is just gorgeous for those summerly long treks in the Scandinavian mountains.
