Product description
Outstanding construction, utmost reliability and super lightweight to boot: the Mammut Sphere UL Winter is the ideal down sleeping bag for challenging endeavors at wintry temperatures. Its high quality down filling and the DWR treated outer material ensure that you will remain perfectly protected even during truly nasty conditions in the mountains.
Mammut have settled for nothing but the very best quality when it comes to the winter sleeping bag’s fill. The Sphere UL Winter is filled with 750 grams of top quality goose down with a high fill power of 800 cu in (at a mixing ratio of 95/5). This provides plenty of warmth right down to sub-zero temperatures. The fill is secured in wave shaped baffles in order to best retain the air that is heated up by the body and to keep the fill in place without dangerous cold spots. A double-layer 9-chamber design provides extra warmth in the foot area.
The down sleeping bag’s outer material is windproof as well as permanently waterproof through DWR treatment. This means that the down retains its full thermal capacity at all times. The ingeniously fitted hood is well sealed while leaving an excellent field of view, allowing you to enjoy the starry sky or the sunrise from your bivouac. The zip works smoothly and is only 3/4 the length of the sleeping bag. This helps to further minimize any loss of heat!
The Mammut Sphere UL Winter is a fantastic piece of equipment for mountaineering, alpine touring, winter trekking and any other activities where both reliable protection from cold temperatures and the packed dimensions and weight of your gear are of vital importance!
