Primus Winter Gas screw-threaded gas cylinders contain the same mixture of propane and isobutane as their Power Gas cylinders, but also a system called Vapourmesh that means they can be used down to –22°C.
Vapour Mesh consists of an absorbent paper inside the cylinder that increases the surface for the evaporation process. Thus, Winter Gas changes from liquid to gas much faster, making it the perfect choice for sub-zero conditions. After 60 minutes of cooking, a Winter Gas cartridge is approximately 9 % more powerful than one without Vapour Mesh. After 120 minutes of use it delivers about 15 % more power.
Contains 80% isobutane and 20% propane. Additive also contains 4 ppm tert-butyl mercaptan odour. Does not contain 1,3-butadiene.
Will fit all Primus and MSR gas cylinder stoves. Not to be fitted to any other type of stove than that they are designed for - make sure that you fully understand your stove's instructions.
We regret that we cannot send gas cylinders via the post - for sale for collection in store only.
