Jet Boil discovered that the secret to a fast and friendly design lies in increasing heat transfer efficiency. Alternating between lab and mountains, a series of designs were subjected to intense experimental and field testing. The result is a product as reliable as it is remarkable; as usable as it is unique. Enabled with the FluxRing heating system, this cup is designed to be placed on the JetBoil stove and then used directly for eating as well, thanks to the heat indicator cozy.
