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.
International standard self-sealing screw-fit connection compatible with most major camping stove brands.
110g size fits inside MSR WindBurner, Primus Lite+, and similar compact stove systems.
Canister also features a very simple float-gauge to determine how much fuel is left.
