Wind is a guarantee when you're in the mountains, and if you've ever tried to boil above treeline, then you know the pain of cooking in the wind. By taking MSR's fuel efficient Reactor stove system and enclosing it in a windproof sleeve, the WindBurner Stove System boils water quickly in winds up to 12 miles per hour. Not only does it make our lives easier in the backcountry, but it saves fuel on those longer trips where every ounce of weight must be carefully considered.
