Expedition sleeping bags
prices on 21 model
— sleeping bags designed for the most severe weather conditions: winter expeditions, high mountain climbs. The comfort temperature in them, usually, is minus, and in the most advanced models it can be measured tens of degrees below zero; they are equipped with hoods and other devices for maximum insulation. Such equipment is not cheap, so it hardly makes sense to purchase an expedition bag for relatively mild conditions (for example, hiking in the warm season).
