MSR - ISOPRO Gas, 227g

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.

Canister also features a very simple float-gauge to determine how much fuel is left.
