The opinion of Aventure Nordique

The Svalbard X-Trem is the warmest down sleeping bag from Helsport. It contains 1180 grams of quality goose down, 800 cuin. Its filling is 11 centimeters thick. It is recommended for a comfort temperature of -29°C. The Pertex fabric is light and water-repellent with a water column resistance of 1000 millimeters. The Tafetta interior fabric is soft to the touch and includes a zippered pocket.


To maximize its thermal performance, this sleeping bag features a slim fit and cold barriers to keep your body warm inside. The flap along the zipper, the collar and the socks around the hood are generous and ensure this thermal barrier. Drawstrings and snaps keep them in place. For ventilation, the three-quarter zip has a double slider.


The 30 denier Pertex Quantum fabric is lightweight and water repellent at 1000 millimeters on the outside of the sleeping bag. The Tafetta interior fabric is very soft to the touch. The sleeping bag also includes a zippered pocket and comes with a webbed compression cover.
