Share your high-tech backpacking stove with friends. The Jetboil Companion Cup allows owners of the Jetboil Personal Cooking System PCS to offer a partner their own heat-and-eat cup. Just like the cooking cup that comes with the PCS, the Jetboil Companion Cup features a built-in FluxRing heat exchanger, drink-through lid, insulating cozy, and measuring cup. It also works great as a separate vessel for preparing side dishes. Those who own the Jetboil Group Cooking System GCS have the option of purchasing the Jetboil Companion Cup for solo trips or outings that emphasize going light. The Jetboil Companion Cup is compatible with the Jetboil Coffee Press, for those who crave a great tasting cup of their favorite brew.
