What reviewers say (out of 10)

Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score

Wind performance*

Reviewers' average 6/10

How well it keeps boiling in a breeze.

7 reviews on wind performance, e.g. "we only had the burner blow out completely once, but there were multiple times it took much longer to boil a pot of water".

Reviewers disagree on this.

Simmer control*

Reviewers' average 5/10

How low the flame turns down without going out, for real cooking.

5 reviews on simmer control, e.g. "Not great for simmering".

In short

Good for

  • Ultralight and fastpacking trips where every gram and litre of pack space counts
  • Summer and sheltered three-season wild camps, boiling water for one
  • Walkers who want the Jetboil FluxRing pot in a much smaller, lighter package

Strengths

  • 201 g by Jetboil's own figure; Outdoor Gear Lab weighed 207 g
  • Stove, stabiliser and a 100 g canister pack inside the 0.8 litre pot (10.8 x 10.8 x 12.7 cm)
  • Jetboil says a 2.5 minute boil; GearJunkie matched it for 0.5 litre, Outdoor Gear Lab measured 2 min 42 s and CleverHiker about 3 min 30 s
  • Titanium burner; Outdoor Gear Lab found it fuel-efficient

Weaknesses

  • Weak in wind: the burner sits on top of the canister, and The Great Outdoors says a full-height windshield is needed
  • No built-in igniter, and the pot is not clipped to the stove, so it can be knocked off
  • No fuel-per-litre figure from Jetboil, so fuel economy cannot be scored
  • The Great Outdoors could not match the quoted boil time in a Cairngorms winter (about twice as long)
