Jetboil makes my favorite cooking systems on the market. I am lazy, and a Jetboil FLASH is a lazy man’s dream. They are super simple to use, easy to setup, extremely fast, very efficient, and lightweight. The FLASH system is new this year, with an improved design over the original Personal Cooking System and a temperature sensitive gel on the side of the cup that shows you when the water has reached the optimal temperature. The FLASH is so efficient thanks to the insulation and Fluxring that it can boil 16 oz of water in right at two minutes, which means that you have your food faster and you save your fuel for more uses per canister.
They have larger systems as well, if you want to do more than just boil water. The Group Cooking System has a larger pot that you can use to cook meals for groups and the Helios has a remote canister setup that allows for cooking in a much wider temperature range compared to regular canister stoves. They even have a Coffee Press for making coffee in your FLASH and other accessories like hanging kits, extra pots, cups, and much more.
