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 IsoPro online. To purchase, please come see us at Moto Liberty. In Store Pick-Up only.
