MSR® IsoPro™ Fuel
MSR IsoPro is a performance-boosting, 80/20 blend of isobutane and propane, with the purest isobutane (5% or less n-butane) of any canister fuel. This clean-burning formulation maintains higher internal pressure at lower temperatures than standard butane/propane mixtures, delivering superior cold weather performance and more consistent output over the life of the canister.

- Clean-Burning: Zero-maintenance combustion.
- Fuel Gauge: Built-in float gauge determines how much fuel is left (110g and 227g canisters).
