Reactor 1.0L Stove System

What Our Gearhead® Experts Are Saying:

"I use the Reactor 1.0L Stove System on every solo or fast-and-light mission. It boils water lightning-fast—even in wind—and everything nests inside so it doesn’t eat up space in my pack. It’s compact, bombproof, and brutally efficient."

When space and weight matter most, we reach for the Reactor 1.0L Stove System. Built by MSR to outperform everything else in its class, this integrated stove-and-pot combo packs down small while punching far above its size in performance. Perfect for alpine soloists and minimalists on the move, it rapidly boils water in just 1.5 minutes, even in high winds and low temps.

The Reactor's radiant burner and enclosed heat exchanger team up to create unmatched fuel efficiency and wind resistance, so we can cook confidently in real-world conditions. Every component, from the stove to the 4oz IsoPro fuel canister (sold separately), fits snugly inside the 1.0L pot for a sleek, self-contained setup. With a BPA-free strainer lid, locking handle, and included PackTowl® Pot Protector, this system is ready to roll wherever you go.
