Melt snow with lightning speed and efficiency, even in the face of wind.

Whip up dinner for a group or melt a heap of snow fast when you're cooking with the MSR Reactor 2.5L Stove System. MSR's engineers gave this system a large, group-friendly pot and went to great lengths to make the burner system utterly reliable and supremely efficient. The enclosed burner shrugs off winds up to 12 miles per hour, the fuel-pressure regulation system maximizes the life of every fuel canister, and integrated stove-and-pot design makes for rock-solid stability when cooking and easy storage when it's time to hit the trail.

  • Stainless steel pot is highly durable and includes a collapsible handle that flips over the see-through lid to keep everything when the system is packed up
  • Radiant burner is enclosed by a heat exchanger that maximizes heat transfer from the burner to the pot so you boil water fast, even in high wind
  • To create a secure, integrated fuel system, the burner locks into the base of the pot, and the fuel canister screws into the base of the burner
  • Burner control twists to open or close the fuel regulator and control heat
  • Internal regulator feeds fuel at a consistent rate for a reliable flame throughout the life of the canister
  • Burner and fuel canister nest inside the 2.5L pot to make this stove compact and easy to pack
  • Package includes: Reactor stove, 2.5L hard anodized aluminum pot, handle, and BPA-free lid
  • Note: fuel canister sold separately

Reactor = Hot water fast

  • Familiarity: I've put it through the wringer

The MSR Reactor is the most impressive snow melting and water boiling devices out there. No other camping stove heats water as fast as this; in my experience more efficiently than a jetboil. Wind is never a factor with the enclosed design, and it is easy to light. It is very efficient with fuel, even in cold weather.

The best feature of the Reactor is the different pot size options. The wide 2.5 pot makes melting snow easier with the wide design. This is the feature that I believe sets this stove system apart from the jetboil.

Fuel can fit conveniently inside the pot with the stove so the only space this guy takes up in the pack is the size of the pot. In addition I have always found it easy to clean, and it does have liter measure markers on the inside of the pot.

I would not think of this guy as a primary cooking stove as heat is harder to control when compared to pocket rockets or whisperlites. That being said it works great for anything involving boiling water, pasta, quinoa, soup, ect. This guy is a snowmelter, and water boiler machine.

Love the stove and have watched it hold up through many expeditions. Remember that when it's cold to keep your fuel warm before you use it as it is very noticeable trying to start the Reactor with a cold fuel can.
