The revolutionary new MSR Reactor stove is the fastest-boiling, most fuel-efficient, stove system ever made. It offers unprecedented canister stove performance in challenging conditions, including superior wind protection and consistent flame output at all fuel levels. It's also compact and easy to use, comprising a patent-pending canister stove and a high-efficiency 1.7-liter pot that makes it great for everything from solo trips to cooking for groups of up to three people. Features: Unrivaled Boil Time: Outperforms the competition in lab tests—boiling 1 liter of water in just 3 minutes—with an even greater advantage in challenging conditions. Maximum Efficiency: Patent-pending radiant burner and heat exchanger make the Reactor the most efficient all-condition stove system, so you carry less fuel. Unmatched Wind Protection: Radiant burner head is enclosed by heat exchanger for total protection in even the windiest conditions. Integrated System: State-of-the-art stove and high-efficiency pot are combined into one compact, easy-to-use system. Consistent Flame Output: Internal regulator equalizes fuel pressure for optimal performance at all fuel levels. Specs: Minimum Weight: 21 oz (595 g) Packaged Weight: 21.6 oz (612 g) Fuel Type: MSR iso Propane/Butane Canister
