Sorry, this product is out of stock. We can notify you when this product is available:

The MSR Reactor Stove System 1.7L is the fastest, most fuel-efficient, all-condition stove system in the world. A pure performance stove! 

With test results to prove it, the Reactor Stove System 1.7L can deliver performance heating in the windiest and coldest conditions. Capable of burning less fuel and allowing you to carry a lighter pack with less fuel whilst moving faster, the Reactor Stove Systems are easy to use and offer proven quality and durability. You can be assured that this performance system will pull you through when you need it most.

Utilising a radiant mesh burner and custom made 1.7l pot/ heat exchanger for the ultimate in high efficiency boiling, it's probably safe to say that there is no finer stove available on the market at the moment to tackle windy conditions, or multi-day trips when a lot of snow needs to be melted. As with all great products the Reactor definitely has it's niche though. For single day 'fast and light', the extra weight of the heat exchanger/pot (only Reactor pots can be used with the Reactor stove) will outweigh the gas saved. Likewise for gourmet campsite cooking there are much more suitable (and cheaper!) stoves available. For its intended use of snow melting, water boiling and 'packet cooking' in demanding conditions though the Reactor is top dog in the stove world.


  • Unmatched Wind Protection: Radiant burner head is enclosed by heat exchanger for maximum protection in even the windiest conditions.
  • Unrivalled Boil Time: Out-performs the competition in lab tests—boiling a litre of water in just 3 minutes—with a far greater advantage in windy 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.
  • Integrated System: State-of-the-art stove and high-efficiency pot are combined into one compact, easy-to-use system.
  • Internal Pressure Regulator: Ensures maximum efficiency regardless of gas levels or conditions.
