MSR IsoPro Series 322100 Fuel Canister, 4 oz
MSR IsoPro is a performance-boosting, 80/20 blend of isobutene and propane, with the purest isobutene (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.
