Fire-Maple FMS-125 PRO

How much it adds to your pack. 3: Below average. Fine for some trips, not others.

Fire-Maple gives 273 g on its US and UK pages (PaleoHikerMD and Aurora Borealis Knives also read 273 g), in the 180-299 g band. Ultralight Outdoor Gear lists 279 g (shop figure), the same band. The hard case is extra.

How much room it takes in your rucksack. 4: A bit below average.

Fire-Maple gives the folded size as 110 mm across and 82 mm high (Φ110 x 82 mm on its UK page, 110 x 82 mm on its US page; Aurora Borealis Knives measured the same). Worked as a round case 11 cm across and 8.2 cm high: 3.14 x 5.5 x 5.5 x 8.2 = 779 cm3, about 0.78 L, in the 0.6-1.59 L band. The page draws it as the box 11 x 11 x 8.2 cm, because two numbers would be read as a roll 11 cm long and 8.2 cm across (0.58 L, band 3), which is not Fire-Maple's shape.

How fast the maker says it boils 1 litre in still air. Wind slows every stove: see Wind performance. 5: Does the job. Average for wild-camping gear.

Estimate from maker's specs

How well it keeps boiling in a breeze, as sold, without an extra windshield. 7: Better than most.

TheOutdoorGearReview says the built-in ring gives some resistance but you need a windscreen in breezy or windy air, and that Fire-Maple's windproof claim is wrong (3); PaleoHikerMD (sent the stove by Fire-Maple) ran a fan test but gives no times, and calls the protection decent but not good, since wind from above would still blow it out (3); Aurora Borealis Knives says the metal ring really helps against gusts (4). None used the 3-6 km/h reference breeze. Fire-Maple's own pages disagree: its UK page claims stable burning up to Beaufort 4 (about 20-28 km/h), while its US page says it is not windproof and the ring only helps against light side breezes. We score wind from the reviews only. Average 3.3 out of 5, so 7 out of 10.
