The opinion of Aventure Nordique

The Spitsbergen X-Trem is a versatile double expedition sleeping bag. It consists of 2 sleeping bags, one down and one synthetic. They can be used in combination to achieve a comfort temperature of -32°C and a comfort limit of -45°C, or independently on colder nights.


Outer sleeping bag (red): Filled with Thermolite T3 Ecomade synthetic fiber. When used alone, it has a comfort temperature of -4°C and comfort limit of -11°C. As it is designed to be used with another sleeping bag inside, it cuts large. On the front is the short zipper, with 2 zips for ventilation. Weight with cover: 1835 grams


Inner sleeping bag (gray): Filled with 860 grams of 750 cuin goose down. When used alone, it has a comfort temperature of -16°C and a comfort limit of -25°C. On the left side is the short zipper, with 3 zips to create either ventilation or an arm opening. On the left side, an opening allows the other arm to be extended. A generous collar with snap fastener closes around the neck. Weight with cover: 1650 grams


The 30-denier Pertex Microlight Ripstop fabric is lightweight and water-repellent on the outside of the sleeping bag. The inner fabric in Pertex Quantum Tafetta is very soft to the touch. Both sleeping bags are equipped with a pocket.
