Ok, the Jetboil isn't the end-all to backpacking stoves. It isn't the lightest option by a long shot. It isn't the most fuel efficient. It isn't the cheapest. It certainly is not the winner for cooking up epic back country feasts (though they do sell some sweet pan attachments that makes this easier to do now). It is damn good at doing one thing: boiling water in a hurry. I have made many users of other stove systems jealous of my ability to have my water at a rolling boil in 2 minutes or less-in any condition-warm or cold, wet or dry, windy or calm.... and have even converted a few anti-Jetboil people into Jetboil users. It hard core wins at convince for the every day weekend warrior backpacker.
In my opinion, for the average backpacker, the Jetboil is the way to go. What isn't to love about a water boiling machine that fits all of the pieces compactly into its special flux ring cup? You can even buy different coozie colors for your cup if you care. Or buy a french press setup if you need coffee like I do. We actually cooked cheeseburgers in the cup last winter. I wouldn't recommend this. But, if it's your birthday and you are camping in the backcountry and just want a goddamn cheeseburger, you figure something out. I also tried to heat a burrito in the cup. I don't recommend it. I burned the burrito and overheated the cup and melted the coozie. Who actually reads the manufacture's instructions or follows them?
Now, which model you want, that's a whole different story. I'll get into that later. For now, observe this glorious gallery of many of the expected and slightly less expected places and ways we have used the glorious Jetboil. This gallery features the Jetboil Sol (the old 4 season model) and Jetboil zip (the basic no frills, less shit to break version). Please, enjoy the gallery!
Now, doesn't that make you want to go out and use (or buy) your own Jetboil?
