Performance-boosting fuel for your canister stove. 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.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
