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.
