With our Winter Gas, we are extending the temperature range for the use of gas cartridges downwards: down to -22°C. The basis for this is the ingenious "Vapour Mesh": an absorbent paper increases the surface area for the volatilisation of the gas. The rapid phase change from liquid to gas makes our Winter Gas a reliable companion on adventures below freezing point. After one hour of boiling, a cartridge with Winter Gas offers approx. 9 % more power than conventional cartridges, after 120 minutes it is even 15 %.
