The MSR WhisperLite International Stove utilizes the tried-and-true proven design of the standard WhisperLite and adds a bit more versatility. It can now run on kerosene and unleaded fuel in addition to white gas. Unleaded fuel right from the pump. You can take this on long thru-hikes or far from camping stores and will still be able to find fuel. Another improvement is the one-piece, stainless steel leg assembly which increases stability and reduces weight. So if you go on longer trips, away from resupplies, and want a stove to adapt to your lifestyle, the WhisperLite International is the stove for you.
