MSR Reactor® StoveSystem

Our largest-capacity Reactor Stove System for serving small groups.

The fastest backcountry water-boiling and snow-melting powerhouses on the planet, Reactor Stove Systems deliver in challenging alpine conditions, where wind and cold can wreak havoc on a stove’s reliability.

Unmatched wind protection: Completely enclosed radiant burner head virtually eliminates effects of wind to maintain outstanding boil times and save fuel.

Maximum efficiency: Radiant burner combines with built-in heat exchanger and internal pressure regulator for best-in-class efficiency in all conditions.

Compact: All systems are self-contained, nesting the stove and fuel inside the pot.

Compatible: Plan for everything from solo to group trips with compatible Reactor Stove System accessory pots in 1.0 L, 1.7 L and 2.5 L sizes.
