Tritium 275

The Tritium 275 is a liner bag designed to connect to the inside of the torpedo sleeping bags in order to boost the temperature performance by approximately ten degrees Celsius.
It is oriented more towards bivouac use than its lighter-weight counterparts, having armholes to allow freedom of movement whilst sitting. It has a fully insulated hood and a short centre zip. 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 5 - 8 degrees Celsius.

Temperature ratings+
The Tritium 275 hasn't been tested for the EN13537 temperature ratings.
We estimate the Deuterium will keep you warm in temperatures down to 5 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.
