Extreme cold sleeping bags below -6°C

These sleeping bags suit extreme cold, winter conditions or high-altitude expeditions, protecting against extreme temperatures.
Extreme-cold sleeping bags may have down or synthetic fill. Down bags retain some compactness and low weight, valuable when trekking. Very warm synthetic sleeping bags are much bulkier but hardier, ideal for damp conditions or open-air wild camps.
