When conditions are at their worst and speed genuinely matters, the MSR Reactor 1.7L Stove System stands apart from everything else in its class. This is the stove you reach for when boiling water fast in cold, windy conditions isn't optional.

The radiant burner, heat exchanger, and internal pressure regulator work together as an integrated system rather than independent components, and the result is performance that simply doesn't exist elsewhere at this price point. The heat exchanger completely encloses the radiant burner head, making wind almost irrelevant to boil times in a way that windscreens and enclosed designs on other stoves can't match. The internal pressure regulator maintains consistent output as temperatures drop and the canister empties, so your first boil and your last boil of the day perform the same. Half a litre of water boils in 1.5 minutes under test conditions, with real-world performance in cold and wind that outpaces the competition by an even wider margin.

The 1.7L system is sized for two or more people, handling both water boiling and snow melting for a group on winter camping and ski touring trips across the Canadian backcountry. Everything, including the stove and fuel canister, nests inside the pot for a compact, self-contained system that goes from pack to boiling faster than any other option available.
