Why carry a pot, a stove, and a cup when you can carry just one Jetboil? The Jetboil stove is a self-contained cooking system that is a little larger than a Nalgene bottle. A super efficient canister stove is locked to a mug to form a single, connected system. Thanks to a patented "Flux Ring" that distributes heat evenly over the bottom of the cup, the Jetboil can boil a cup full of water in 30 seconds. The Companion Cup version of the Jetboil PCS simply comes with an extra cup for ultralight backpacking with two people. The Jetboil's cup can be removed and switched so you can cook two portions separately. The base and canister nest inside one of the mug for transport and both have insulating sleeves to protect your hand and hold heat inside. A handgrip strap gives you something to hold onto so the hot stuff goes into your mouth, not your lap. Fuel canister not included.
Bottom Line: The smallest two-person cookset around.
