Radioactive range
Protium 135
£249
Including UK VAT.
The Protium 135 is a liner bag designed to connect to the inside of the Torpedo sleeping bags in order to boost the warmth by three to five degrees Celsius.
It is the lightest and most basic style in the Radioactive range. It has no side zip or 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 in summer), it has not been tested for the EN (European Norm) standards and has no official temperature rating, but we expect this would be in the range of 12-15 degrees Celsius.

Temperature ratings+
The Protium hasn't been tested for the EN13537 temperature ratings.
We estimate the Protium 135 will keep you warm in temperatures down to 12 - 15 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.
