MSR® WindProTM II Stove combines the stability and wind protection of a remote-burner design with the convenience of canister fuel. Unlike other canister stoves, the WindProTM II is capable of running on liquid-feed direct from the canister. That means you can run it in the traditional upright position for optimal efficiency, or flip it over to deliver liquid gas directly to the burner. What's the advantage? It boosts the Stove's output. Speeds up heat times. And improves its performance in cold weather, or low-fuel scenarios.
