Yes, with a little planning. All canister stoves lose power in the cold because colder gas has lower pressure, which can mean slower boil times and a harder-to-light igniter. JetPower fuel's propane blend helps reduce these effects.

To get the best performance:

• Keep your canister warm in a jacket pocket or sleeping bag, and take it out just before cooking.
• Stand it on a piece of foam rather than snow or cold ground.
• Carry a spare canister kept warm to swap with a cold one.
• Always pack matches or a lighter as backup.

With the canister kept warm, Jetboil stoves still perform reasonably well at around -18°C. Altitude isn't a major issue and can even help. Jetboil stoves have been used as high as 8,000 m on Mt Everest.

If you regularly cook below about 7°C, consider the TrailCook 1.2L or TrailCook 2.0L. Their built-in regulator delivers consistent heat down to -6°C.

JetPower is a blend of propane and isobutane. Propane gives higher vapour pressure for better cold-weather performance, while isobutane keeps pressure steady as the canister runs low. The 100gm canister is also sized to pack neatly inside your Jetboil cup.

Jetboil systems can be up to twice as efficient as conventional stoves, so you can carry less fuel for the same trip. A 100gm JetPower canister boils roughly the same amount of water in a Jetboil as a 227 g canister does in many other stoves. That means less weight, less bulk and less money spent on fuel.
