Sumo Cooking System

The expedition kitchen for the whole rope team.

The Jetboil Sumo Cooking System is designed to bridge the gap between fast-and-light alpinism and basecamp comfort. It integrates the high-capacity performance needed to melt snow for a group with the delicate simmer control required to cook real meals, not just rehydrate mush. Built around a massive 1.8-liter vessel and Jetboil's proprietary regulator technology, the Sumo delivers consistent heat output even when temperatures drop well below freezing, ensuring your team stays fueled and hydrated whether you are dug in on a glacier or waiting out a storm at a high camp.
