No subject to promotional offersThe MSR Reactor 2.5L Stove System is the one with the highest capacity of the Reactor range.
It is perfect for a small group of friends or family, for up to 2 to 4 people, and allows you to cook a good amount of food or melt snow extremely quickly. It is a high-end stove to bring on each and every one of your trails or even in high-mountain.
This extremely fast stove system boils half a litre of water in 1 min 30 only. This is also true under real conditions since the radiant burner head is protected from the wind. For better performance and reduced fuel consumption, it features a heat exchanger and an internal pressure regulator. The powerful Reactor systems are just as light and small once nested, and will never clutter up your bag.
This system is supplied with an extremely lightweight 2.5L pot with a hard anodized aluminium construction.
It is also delivered with a BPA-free transparent strainer lid and its folding handle.

Pros:
Integrated System: state-of-the-art stove and high-efficiency cookware are combined into a compact, self-contained and easy-to-use system.
Unrivalled Boil Time: outperforms the competition in head-to-head lab tests—boiling 0.5 litres of water in just 1.5 minutes—with an even greater advantage out in the real world.
Unmatched Wind Protection: heat exchanger completely encloses radiant burner head, virtually eliminating the effects of wind to maintain outstanding boil times and save fuel.
Maximum Efficiency: patent-pending radiant burner, heat exchanger and internal pressure regulator produce best-in-class, fuel-sipping efficiency in all conditions.
Compact: all systems are self-contained, fitting the stove and fuel inside the pot. (1.0L Reactor System nests optimally with our new, smaller-diameter 113g 4 oz. canisters.)
