冬季瓦斯罐；Primus

Finally, a gas canister that actually works below freezing. Used it on a week-long ice fishing trip and the flame stayed strong even at -10°C. The ability to maintain consistent pressure in the cold is a game-changer.

Took this canister on a backcountry ski trip and the stove kept a steady flame even when the mercury dropped well below freezing. The gas mix clearly works better than the standard stuff I've used in past winters.

Fired up the stove at -10°C and it roared to life instantly — no sputtering or weak flame like with standard canisters. The mix really does keep the pressure stable when the thermometer drops.
