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.

  • 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 (4oz and 8oz canisters)
