Expert Insights
This "new for 2025" release of the Jetboil Flash Java Kit provides an improved burner design and valve mechanism that allow for one-handed ignition and flame adjustment. With its water-carrying capacity of a full 1.0L, it easily supports making coffee for up to two folks and rehydrating even the largest, most water-demanding freeze-dried meals (i.e., Peak Refuel Biscuits and Gravy).
The long-standing Jetboil Flash Java Kit has been PROVEN across varying backcountry crowds, to include our backcountry hunting community. Time well tell if the new burner-and-valve design will prove equally durable, but one thing is for certain, Jetboil is known for producing products that last for 10+ years of frequent use. So, we are confidently hopeful!
