Summary:
The Jetboil Sumo Stove is part of the Jetboil system of burners, pots and accessories. The Sumo boils water in two to four minutes, and is well-suited for a quick meal of coffee and oatmeal, or packaged noodles. The stove is self-contained, with components that nest together, although some of the components are fragile and fitting everything back together can be a little complicated. The reliable push-button lighter makes it easy to light the stove with no flare-ups.
