Deuterium 200


The Deuterium 200 is a liner bag designed to connect to the inside of the Torpedo sleeping bags in order to boost the warmth by five to seven degrees Celsius.
It is the most popular and versatile style in the Radioactive range thanks to its short side zip and simple hood. The baffles are stitched-through and it is supplied with a stuff-sack. As this was not designed as a stand-alone bag (although it can be used as such), it has not been tested for the EN (European Norm) standards and has no official temperature rating, but we estimate this would be in the range of 8 - 10 degrees Celsius.

We estimate the Deuterium will keep you warm in temperatures down to 7 - 10 degrees Celsius.

Care & Attention

Down is a very resilient insulating material and, with basic care, any down sleeping bag should last you a very long time (if not your entire active climbing life).

There are two simple rules to ensure longevity:
1. Always store your sleeping bag uncompressed in a dry, airy place
2. Always use a sleeping bag liner. This will prevent the bulk of body oils and perspiration from getting into the down itself and reduce the need for washing the bag.
