MSR IsoPro is an 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, giving you superior cold weather performance and more consistent output over the life of the canister.

This 4 oz. canister is sized to fit inside the MSR 1.0L Reactor® Stove System.

  • Clean-Burning: Zero-maintenance combustion
  • Fuel Gauge: Built-in float gauge determines how much fuel is left
  • Recyclable (consult your local recycling center for regulations)
