MSR IsoPro Canister Fuel

MSR IsoPro contains 80% isobutane and 20% propane, making it the purest canister fuel available with 5% or less n-butane. This mixture generates higher internal pressure at lower temperatures for consistent, performance-boosting output. The 4 oz. canister is designed for use with the 1.0L WindBurner and Reactor Stove Systems. Clean-burning combustion and a built-in float gauge provide easy use and maintenance, while recyclability is subject to local regulations.
