The MSR Reactor 1.7L Stove System is the world's fastest, most fuel-efficient all-condition canister stove engineered for backpackers and mountaineers who refuse to let cold, wind, or altitude slow them down. Whether you're melting snow at base camp or cooking a hot meal after a long alpine day, the Reactor delivers unmatched performance where it matters most.

Why the MSR Reactor 1.7L?

The ideal all-around choice for two-person backcountry trips. With a 3-minute boil time per liter and the ability to boil 22 liters of water per 8 oz. fuel canister, you'll carry less fuel and move faster than with any other stove on the market. The integrated heat exchanger fully encloses the radiant burner head, virtually eliminating wind's effect on performance so your stove works just as fast at 10,000 ft in a storm as it does at the trailhead.
