Msr Iso Pro

Msr gas cartridge with screw valve. This high-quality, environmentally friendly Iso Pro TM fuel consists of 80% isobutane and 20% propane, enhancing the performance of cartridge stoves. It burns residue-free, resulting in minimal soot and reducing blockages to a minimum. The gas mixture maintains a higher internal pressure at lower temperatures compared to standard butane/propane mixtures, providing consistent performance even in cold conditions throughout the cartridge's lifespan.
