MSR IsoPro™ Fuel Canister (4oz, 113g)

Performance-boosting fuel for your MSR canister stove.

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)
