MSR Reactor® Stove Systems (Various Sizes)

The Reactor Stove System is designed to be the fastest and most fuel-efficient option MSR offers, delivering dependable performance in cold, windy real-world conditions. It combines a stove with high-efficiency cookware into a compact, self-contained system you can trust on backcountry trips.

• Integrated System: State-of-the-art stove and high-efficiency cookware are combined into a compact, self-contained, easy-to-use package that keeps everything you need in one place.
• Unrivaled Boil Time: Boils 0.5 L in about 1.5 minutes in lab tests, with real-world advantages that speed meals and hot drinks while saving fuel.
• Wind-Resistant Heat Exchanger: Heat exchanger fully encloses the radiant burner head, dramatically reducing wind effects to maintain strong boil times.
• Maximum Efficiency: Patent-pending radiant burner, heat exchanger, and internal pressure regulator optimize fuel use across conditions for consistent performance.
• Compact, All-in-One Design: Self-contained systems store the stove and fuel inside the pot; nests with the smaller 4 oz canisters (sold separately) for streamlined packing.
• 1.0L System: For trips with 1–2 people or when 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 people.
• 2.5L System: Boils enough for five freeze-dried meals at once, or makes an expedition snow-melting powerhouse for 2–3 people.
• Includes Essentials: Reactor Pot and Stove, BPA-Free Strainer Lid, PackTowl® Pot Protector, and folding/locking handle for easy transport and use.

With the Reactor Stove System, you’ll burn less fuel and carry less fuel, enabling faster travel and more cooking opportunities on the trail. The wind-proof design keeps performance reliable in exposed conditions, while the integrated setup reduces gear clutter and setup time. Choose the 1.0L for solo or lightweight trips, the 1.7L for couples or winter adventures, or the 2.5L for group meals and snow-melting capability, and you’ll have a versatile, durable system built to perform when it matters most.
