The fuel in your canister stove has a direct effect on how it performs in the cold, and MSR IsoPro is the cleanest-burning, highest-performance canister fuel available for getting the most out of your MSR stove system.

The 80/20 isobutane/propane blend maintains higher internal canister pressure at lower temperatures than standard butane/propane mixtures, which translates to more consistent output and faster boil times on cold Canadian mornings when a standard canister would already be losing pressure. The isobutane used is among the purest available at 5% or less n-butane, contributing to cleaner combustion and zero-maintenance performance across the life of the canister. The 16 oz size is well suited to extended trips or group use where a smaller canister would run out mid-trip.

Please note: due to hazardous materials shipping restrictions, IsoPro cannot be shipped. Available for in-store purchase or online ordering for in-store pickup only.
