Re: Cold Weather Backpack Stoves
A Coleman Peak 1 white gas stove is great to even -50 F. White gas is utterly reliable in winter. I have an MSR Dragonfly that can use white gas (Coleman Fuel), auto unleaded gas or, if you change the jet size, kerosene or jet fuel.
It's the canister isobutane gas stoves that struggle in very cold weather, even the "upside down" cylinder setups when it's around -15 F.
