The same jacketed cup that comes with the Jetboil Sumo Cooking System, the 1.8L Companion Cup lets you expand the capacity of various Jetboil Cooking Systems without adding the weight of extra burners or fuel cartridges. Ideal for larger groups, or smaller groups insistent on more sophisticated dining!
The FluxRing heat exchanger underneath the cup deliver astonishing heating efficiency, while the insulating neoprene cosy helps to keep the heat in the cup.
The cup supports a myriad of packing configurations. It stows a 100g or 230g Jetpower Fuel Cartridge and burner base with room to spare, or a complete Sol or Zip system with 100g fuel. It is also capable of stowing a 450g fuel canister. The bottom cover doubles as a measuring cup and bowl.
