Fast, windproof heat that folds to the size of your palm. Choose your burner: the copper-core cyclone concentrates a swirling vortex flame that shrugs off wind and boils a liter in about 3 minutes, while the infrared models burn flameless through a glowing ceramic plate — virtually windproof and about 15-20% more fuel-efficient. Both styles fold flat around a 304 stainless steel chassis, light with a push-button piezo igniter, and hold pots up to 22 lbs. They run on standard threaded isobutene/propane canisters (MSR IsoPro, Primus, Jetboil) and weigh under a pound in the included hard case. From boil-in-the-dark mornings to wind-whipped ridge tops, this is the stove that makes camp coffee happen.
