The finest down for a hotel under the stars. At the request of the Mammut Pro Team athlete Dani Arnold, we have developed a sleeping bag for bivouac nights on a north face. The Mammut Sphere Nordwand is an extremely light 3-season sleeping bag designed to fit in any backpack as an essential item on all long extreme tours. The premium-quality thermoactive-coated down with an amazing 950 cuin puff strength reflects the body’s heat and provides excellent insulation. Wave-shaped chambers prevent the fine down from slipping to create cold bridges. To make sure no annoying spindrifts disturb your sleep, the SuperDRY™ water-resistant technology keeps both the down and you dry. The hood sits like a beanie on your head, guaranteeing a perfect view of the next pitch even when completely closed.
