in Customer Rewards when you buy this item today

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

MSR Reactor Stove System




Not only is the Reactor Stove System the fastest and most fuel efficient stove ever made, it’s the only one that delivers that level of performance in the cold and wind of the real world.  Simply put, you’ll burn less fuel, carry less fuel, and move faster than with any other stove available. And with MSR’s proven quality and durability, you can be assured of that performance to pull you through when you need it most.

  • Integrated System: State-of-the-art stove and high-efficiency cookware are combined into a compact, self-contained and easy-to-use system.
  • Unrivaled Boil Time: Outperforms the competition in head-to-head lab tests—boiling .5 litre 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 4 oz. canisters, which are sold separately)

1.0L System: For trips with 1-2 people, or anywhere weight and space are at a premium.

1.7L System: All-around performer with the capacity to boil water and melt snow fast for two or more.

Both Systems Include: Reactor Pot and Stove, BPA-Free Strainer Lid, PackTowl® Pot Protector, and folding/locking handle
