There is a new camp cook system in town, the all-new Jetboil Stash Cooking System – designed to be efficient and compact, maximizing your pack space without sacrificing performance.

Jetboil released their first cooking system combined a burner, pot with a built-in heat exchanger almost twenty years ago. It was a glorious success, easy to use, fast boiling, and fuel-efficient, and since then, there have been many Jetboil stove systems. One thing that always held back the Jetboil system – the weight. So the Jetboil Flash looks like a fantastic addition – releasing a genuine ultra-lightweight stove.

Jetboil Stash Cooking System Includes

The Jetboil Stash Stove Set includes a stand-alone stove with a titanium burner and a 0.8L FluxRing Anodised Aluminium Cook Pot. This new cooking system maximizes your pack space without reducing that iconic boiling speed and performance. Just like previous Jetboil models, the Flash is up to 2x more fuel-efficient compared to conventional stoves.

Jetboil Flash Burner

Stash Cooking System Burner Review

The burner head of the stove is made of titanium. It doesn’t come with a regulator; Jetboil says it’s best for boiling rather than simmering food. There is also no piezo igniter, which I don’t think is a problem as they often fail, and a pocket lighter or two is a more reliable option. There is even a space between the bottom of the fuel canister and the lid to stow your lighter.

You’ll also get a small bag to store the burner in. If you have another pot at home, it can also be used with this burner, another key feature we like as this isn’t the case with other Jetboil stove systems. A canister stabilizer is also available if needed. It adds 0.9 oz to the weight. The cooking pot clicks onto the burner, and the unit feels stable without the need for the stabilizer.

Jetboil Stash Weight & Size

Stash Cooking System - Lightweight

The Jetboil Stash is the lightest Jetboil stove system by far. At only 7.1 oz, the whole cooking system boasts 40% weight savings vs. the Jetboil Zip or MicroMo and about 45% weight savings vs. the Jetboil Flash.

The actual stove itself on the Stash weighs 2.82 oz, and the cookpot 4.23 oz. Boiling times on the Flash cooking system are 2 mins and 30 sec for 0.5-Liters of water.

Jetboil Stash Cooking System Design

Jetboil has reduced the weight by simplifying the design and reducing the weight of specific components. In particular, the bulky plastic collar that links the burner and pot has gone. Instead, the pot fits onto the serrated arms of the burner. This design feature reduces wind resistance and makes it easier to remove the pot from the burner – no twisting is needed.

Wider Cooking Pot

A second feature that I like is the pot’s shape, which is now wider than it is tall. This shape makes it easier to use as a bowl or mug and better for stirring food than the taller narrow pots found on most. This shape makes it more stable too. Unlike other Jetboil stoves, the Flash’s pot doesn’t have an insulating sleeve to save weight.

Boiling Time Jetboil Stash Vs. Flash

In terms of boiling speed, it is not as fast as the Flash’.which has 9,000 BTU, blowtorch heat, and boils 0.5 L in 100 seconds vs. the Stash 4,500 BTU’s boil time of 150 seconds. However, the Flash’s boil speed comes at a cost. The Flash is 20% less fuel-efficient compared to the Stash.

The Final Verdict - Jetboil Stash Cooking System

What I particularly love is how light it is. I like Jetboil stoves and have used them on short trips but never on long ones due to the weight. However, few gas burners weigh less than Stash’s 2.1 oz, so this is a real contender to win the hearts and minds of ultralight thru-hikers.

I think it’s the ideal size for solo use and just big enough for two if you’re not making huge meals. The Jetboil Flash is an impressive new stove system.
