Jetboil Stash vs MSR Reactor 1.7L Stove System

The Stash is the ultralight solo pick: 7.1 oz, a nesting 0.8L pot and fast boils, and owners like it for one-person trips. The Reactor 1.7L is the better stove for two people, cold weather and wind, with a 1.7L pot, 9,000 BTU and a shielded radiant burner that stays lit in a breeze. Reviewers of the Stash praise weight and fuel use but report wind blowouts and occasional clogged jets; the Reactor is heavier and bulkier but widely trusted for reliability in bad conditions.

• Choose the Jetboil Stash if you backpack solo, count every ounce and mostly boil water in calm weather.
• Choose the MSR Reactor 1.7L if you cook for two, melt snow or camp where wind and cold are routine.
