Pure & Dry Sleeping Bags

Pure & Dry expedition sleeping bags are constructed with an all over lightweight, waterproof outer (Tundra Waterproof Lightweight Fabric) of 73 gram per metre which supports a 10000mm water column. They are filled with the highest quality ethical down from Poland where down is harvested from the nests of naturally moulting mature birds.

The minus 30 and minus 40 bag in the Pure & Dry sleeping bag range are suitable for use in extreme racing conditions such as the Iditarod Great Sled Race.

Our Pure & Dry expedition sleeping bags are handmade in Warsaw, Poland to exacting standards by highly skilled workers. The design employs all the technical features you could possibly expect from an expedition sleeping bag. Check the exhaustive feature list below or read more in our technical guide.

Women wishing to order this sleeping bag may wish to choose the shorter length (180cm) sleeping bag which is available as a special order. It takes no longer to produce and includes the same fill weight of down as the longer 195cm sleeping bag. Find out more on the Women’s Sleeping Bags page.
