Jetboil - Joule

The Jetboil Joule Group Cooking system offers unparalleled cold weather performance and ease of use for backpacking groups and alpinists. Joule is the world's fastest cooking system, offering consistent heat output down to 10° F (-12° C) thanks to a proprietary regulator technology.
Joule's innovative design with inverted fuel can and liquid feed regulator provides performance matching liquid and multi-fuel stoves, but with the ease of use and versatility of canister systems. Joule's 10,000 BTU burner provides the raw power for rapid boil times of 2 minutes 40 seconds (per liter) and still offers excellent simmer control for other cooking needs.
The Joule comes with a 2.5 Liter insulated FluxRing vessel that has a stable locking handle that folds for storage and a convenient push-button igniter. Also available is the Alpinist Accessory kit which comes with a windscreen and hanging kit (Sold separately.)
