MSR IsoPro Fuel - Threaded Gas Cartridge - 227g

The MSR® IsoPro™ gas cartridge optimizes the performance of cartridge stoves with an 80/20 blend of isobutane and propane. Compared to other gas cartridges, it contains the purest isobutane (5% butane or less). The fume-free burning mixture maintains a higher internal pressure at lower temperatures than common butane/propane blends, providing superior cold weather performance and more consistent performance over the cartridge life.
