The Jetboil Stash is the lightest option in their range of well-established stove systems. This all-in-one system containing a FluxRing cook pot, titanium burner, lid and stand, fits neatly together weighing only 232 grams. With an added 100-gram gas canister and a lighter, the total carried weight comes in at 456 grams.

This can certainly be regarded as a compact option for lightweight expeditions and although mostly aimed for solo use we found the 0.8 L pot size adequate for two people. This well thought out and designed system, along with the obvious build quality is a great feature of the Stash, perfectly fitting into life with us from wild camping to bike packing and pack rafting expeditions.

When in use each section of the pot and burner seats neatly together and is very easy to assemble with instructions located on the burner storage bag. The height of the stove could be an issue when placed on uneven ground although the pot support spreads out the weight for added stability.

The FluxRing technology Jetboil claim to “ensure a rapid 2.5 Min boil time.” This works by evenly spreading the heat throughout the base of the pot to increase efficiency.Obviously, there are many factors that can affect the performance of a stove, the UK has ever-changing windspeeds and temperatures. The available water source and type of gas used also contributing large factors.

We ran two separate tests to see how the Stash would perform, both using Jetboil’s own all season fuel. The first being a typical autumn nights camp with a temperature of around 4 degrees, stove sat in the awning of our tent with just a slight breeze, and water collected from a nearby burn. 500ml of water boiled in a time of 3mins 46secs.

The second test was taken on a cold winter camp at just below 0 degrees, stove seated in our snow hole, no wind, using snow as our water source. 500ml of water boiled in a time of 7mins 48 secs.

The results vary by a large amount and it’s safe to say there were no surprises that the Stash is better suited for summer use (where we would expect a closer boil time to the 2.5 min Jetboil have claimed), although did surprise us and performed to a workable standard in winter. Typically, we found that when boiling water for meals and hot drinks for 2 people, a single 100gram canister would suffice for 2 days.

In terms of performance in windy conditions and like most burners with little wind protection like the Stash, increased windspeeds are always going to be an issue. We included a small titanium wind deflector which did solve part of the issue but expect boil times and gas consumption to increase significantly.

It must be noted that the burner has no regulator so is not a stove you are going to make many meals with from scratch. We’d say you’d just about get away with a pasta and sauce, although the Stash is much better suited to quickly boil water to be added typically to dehydrated meals. There is a twist adjusting valve, although even on its lower setting it’s hard to achieve a simmer without easily losing a flame. We did have an issue with the wire on the valve, that started to detach itself from the small slots. This may just be an issue with the stove we received, although trying to click it back in place in colder weather is fiddly and became annoying at times.

The pot itself is wide enough that you can eat and drink straight out of to save on the added weight of an extra cup or bowl. We much preferred to pour the boiled water into a lightweight cup or meal pouch as these are easier to clean and lessens the wear and damage to the pot.

The lack of an integrated ignition we found to be a strange choice from Jetboil as this is often included on many of there other stoves. The choice of a soft plastic lid was also an interesting but confusing addition. We very much liked the inventiveness of the lid having an indent to hold a gas canister for easy transportation whilst also mitigating the annoying rattle a stove system can make whilst travelling. When it comes to use as an actual lid, the hold we found to be a poor, and needed the use of a thumb to keep it from falling off whilst pouring water through the spout.

Our Verdict
The Jetboil Stash is a great all in one compact stove system, with an interesting storage system, and a decent burner producing quick boil times with low gas consumption. Apart from a few niggles the overall design is nicely constructed, easy to assemble and with the added stabilisation a study stove for its size. The issue the Stash presents is that it slots right in the middle of most stove choices. If you want a burner for boiling water quickly there are better options for faster boil times and lower gas consumption. Yes, they may be slightly heavier and less compact, but the alternatives will out do the Stash in a variety of conditions. The Stash in this instance would be a choice on weight and pack size alone and certainly fitted best for us when travelling by bike or raft. The lack of a regulator to allow a simmer and more options for meal choices will also be factor, with a DIY set up being better suited if you want a compact stove with a variety of cooking options. Overall, the Stash is a decent stove and for most will make a great companion for lightweight expeditions.
