MSR® IsoPro™ Fuel — 8 oz. Canister
Colour selected: None
Colour selected: OS
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. Due to hazardous materials shipping restrictions, we do not sell MSR IsoPro online. To purchase, please visit your nearest Macpac store.
