IsoPro Fuel Cartridge 110g - 450g

IsoPro Fuel Cartridge 110g - 450g

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.

  • Three Sizes: Sold in 4, 8 and 16 oz. canisters to meet the demands of any stove or trip. The 4 oz. canister is sized to fit inside the 1.0L WindBurner® and Reactor® Stove Systems.
  • 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).
  • Recyclable: Consult your local recycling center for regulations.

Please Note Gas cannot be shipped outside the island of Ireland
