Running the right fuel in your canister stove is one of the easiest ways to improve cold-weather performance, and MSR IsoPro delivers the cleanest-burning, most consistent output available for any canister stove setup.

The 80/20 isobutane/propane blend maintains higher internal pressure at lower temperatures than standard butane/propane mixtures, keeping your flame strong and boil times consistent on cool Canadian mornings when a lesser canister would already be losing steam. The isobutane purity level of 5% or less n-butane means cleaner combustion and zero-maintenance performance across the full life of the canister. The 8 oz size is a practical choice for weekend trips and solo outings where a 16 oz canister is more than you need and a 4 oz runs out too quickly. The built-in float gauge lets you check remaining fuel without guessing.

Please note: due to hazardous materials shipping restrictions, IsoPro cannot be shipped. Available for in-store purchase or online ordering for in-store pickup only.
