MSR IsoPro Fuel Size:450g / 16oz durable and highly water-resistantDue to hazardous materials shipping restrictions, we do not ship this product. 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.
