Our Thoughts & Overview

The Jetboil Flash is the go-to personal cooking system for fast, reliable meals and hot drinks on the trail. Whether you’re brewing a morning cuppa, warming up soup, or rehydrating your evening meal, the Flash delivers a rapid boil in just 100 seconds – the fastest Jetboil ever made.

Its 1-litre FluxRing cooking cup with insulating cover keeps water hotter for longer, ideal for changeable UK weather. The newly updated push-button igniter gets things going straight away, no faffing with matches or lighters & has a great sturdy feel to it. Here at Otimos one of our favourite features has to be the colour changing heat indicator which visibly lets you know when your water hits boiling temp.
