MSR Reactor 2.5 L Stove System

An all-condition canister stove system with a 2.5‑litre anodized aluminium pot and integrated heat-exchanger. Designed for small groups (typically 2–4 people) who need fast boil times, fuel efficiency and wind resistance.

Benefits

• Integrated radiant burner and profiled heat-exchanger pot for fast boil and efficient heat transfer.
• Windproof design covers the burner with the pot’s heat-exchanger to resist gusts and reduce flame loss.
• Internal fuel-pressure regulation maintains a steady flame across varying conditions.
• Compact nesting: the stove and an 8‑oz canister nest inside the pot for convenient packing.
• High fuel efficiency reduces gas consumption during normal cooking; canister sold separately.

Suitable for hiking and year-round or winter expeditions in both exposed and broken terrain where wind resistance, rapid boiling and fuel economy are important.
