Fuel for your canister stove. A self-sealing valve allows removal of partially consumed canisters for packing or travel. This fuel cartridge has a 4-season mixture: 70% Isobutane, 25% Propane and 5% Butane. The mixture of isobutane and propane keeps a good efficiency even at cold temperatures. It offers much better performance than butane/propane canisters.
