Product Info for MSR Reactor 1.0L Stove System

The new MSR Reactor Stove is the fastest boiling, most fuel efficient windproof stove available. The stove combines a state-of-the-art stove and high efficiency 1.7 liter pot with heat exchanger into one compact, easy-to-use unit. The Reactor is also the first canister stove to use an internal pressure regulator that ensures consistent flame output in all conditions. The radiant burner is enclosed by the heat exchanger for total wind protection, making the Reactor the perfect stove for windy and cold conditions. The Reactor is also great at high altitudes. You'd expect a stove like this to be pretty heavy and not great for backpacking, but the Reactor 1 L weighs in at only 16.7 oz and it stows away into itself.image
