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.

  • Improved Performance: 80/20 blend of isobutane and propane delivers superior performance throughout the life of the canister and in colder temperatures.
  • Clean-Burning: Zero-maintenance combustion.
  • Fuel Gauge: Built-in float gauge determines how much fuel is left (4 oz. and 8 oz. canisters).
