Make the most of every ounce of fuel you carry when you cook with the MSR Reactor 1.0L Stove System. MSR's engineers went to great lengths to make this stove efficient with built-in windscreens, a burner that boils water quickly, even in high wind, and a fuel regulator that stretches every canister of fuel just a little further. Ideal for a solo backpacker, this compact system uses a nesting configuration that allows you to slide the fuel canister and burner inside the pot for easy, contained storage.
