The three models in the Caucasus range offer weight and warmth options to cover most trekking adventures. Thanks to the high quality down filling, they are extremely compressible, making for a small pack size, and come with their own waterproof roll-top compression sack to make sure the down stays dry no matter what the on-trail conditions. With their highly technical construction and down fill, the Caucasus range offers the best ratio of warmth to weight of the whole sleeping bag collection.
