Cumulus Alaska 1300

If you are looking for a sleeping bag that will protect you against severe weather conditions, this is the best choice. It was a piece of equipment used during expeditions to K2 and Shisha Pangma. Alaska 1300 was used at an altitude of 7800 m, which is reputed to be the highest winter level for using any sleeping bag. Weighing slightly more than 1,9 kg, it is still very lightweight. The volume of spread empty sleeping bag is about 0,3 m³, i.e. it expands up to 15 times after taking it out from the stuff sack.
