Jetboil Stash
Jetboil Flash (comparison)
The Jetboil Stash is the lightest Jetboil ever made — a complete 0.8L integrated system at just 7.1 oz. Jetboil designed it for gram-counting ultralight backpackers who still want the FluxRing efficiency advantage. We tested it against the Flash and the MSR PocketRocket 2 over 4 days in the desert.
💡 Quick verdict
The Stash delivers Jetboil efficiency at MSR PocketRocket weight. It trades the igniter, the boil indicator, and 0.2L of volume to get there. For ultralight purists who want fast boils without the Flash's bulk, it's a genuine option.

Weight analysis
The Stash at 7.1 oz (system) is almost half the weight of the Flash (13.1 oz). But the comparison with the PocketRocket 2 is more nuanced: the PocketRocket alone is 2.6 oz, but you still need a pot (typically 3–6 oz for a titanium option). The Stash system (stove + pot) ends up roughly competitive with PocketRocket + light titanium pot, while offering better wind resistance and fuel efficiency.
Performance
The Stash's FluxRing pot gives it Jetboil-level efficiency — we measured roughly 10–11L boiled per 100g of fuel, similar to the Flash. Wind resistance is strong due to the integrated cozy and pot design. The 0.8L volume is enough for one person's meal and hot drink, but tight for two servings.
Pros
- 7.1 oz — lightest Jetboil by far
- FluxRing efficiency: fast boil, excellent fuel efficiency
- Strong wind resistance from integrated design
- Nested system — everything stores in the cup
Cons
- No igniter — bring a lighter
- No boil indicator — watch it manually
- 0.8L is small for two people
- No simmer control
- Same price as the Flash despite fewer features
Frequently Asked Questions
- Is the Jetboil Stash worth it over the Flash?
If weight is your top priority, yes. The Stash saves 6 oz over the Flash with nearly identical fuel efficiency. If weight isn't critical, the Flash's igniter and boil indicator make daily camp life easier.
- Is the Stash compatible with Jetboil accessories?
The Stash uses a slightly different form factor than other Jetboil cups and has limited accessory compatibility. Check compatibility before purchasing Jetboil accessories.
Verdict
The Stash is the right choice for ultralight backpackers who want Jetboil efficiency without the Flash's weight. If you're counting every gram and primarily boil water for freeze-dried meals, it delivers. Everyone else should consider the Jetboil Flash or Jetboil Zip.
