SOTO WindMaster Review

Last updated:

The SOTO WindMaster is a 3.0 oz canister stove that keeps boiling in wind and simmers better than its rivals. Buy it if you cook; skip it if you only boil water.

BIKEPACKING pointed a hairdryer at two stoves. The SOTO WindMaster took about twice as long to boil a liter. The MSR PocketRocket 2 never got its water past 50°C. That's the WindMaster's whole argument, and I find it hard to argue with.

My call, once. Buy it if you cook real food at breezy three-season camps and you want a low flame you can use. Skip it if every ounce counts, if you only boil water, or if your trips go well below freezing. I give it 8.5 out of 10.

Who is the WindMaster for?

It's for the cook. SOTO's current OD-1RXN pairs the burner with a removable four-arm pot support, the 4Flex, which folds out to 142 mm across, by BIKEPACKING's measure. BIKEPACKING used pots up to 2 L on it with zero deflection, and OutdoorGearLab says it easily supports cookware larger than 1 liter. SOTO's own limit is a 2 L pot, with no more than 1.5 L of liquid and under 3 lb. On a small 110 g canister, SOTO says to keep the pot to about 1 L. I like that SOTO prints a liquid limit at all. 1.5 L. Under 3 lb. Specific.

That broad platform is what a skillet or a wide pot needs. A three-arm minimalist stove is happiest under a narrow mug.

Skip it if you count every gram, or if your routine is boil, pour, wait. BIKEPACKING notes the stove and its support don't nest as well in slender one-person pots, and an integrated system does the boil-only job more simply.

How good is it in wind?

Resistant, not immune. The burner sits recessed behind a raised lip, so the wind can't reach the flames directly. In BIKEPACKING's hairdryer test the WindMaster took about twice as long to boil a liter, which also means about twice the gas. The PocketRocket 2 in the same test never got the water above 50°C. BIKEPACKING also couldn't light a Bic in that airflow, and the WindMaster's piezo lit it fine.

I'll admit the 50°C line is my favorite number in all the stove reviews I've read for this site. It isn't a boil time. It's a stove failing to boil. That's a different kind of evidence, and it's the one I'd remember on an exposed ridge.

OutdoorGearLab tested with a fan and measured about a 15% drop in fuel efficiency. Its wind score is 7.9 out of 10. The two methods aren't the same, but they point the same way: it keeps working when open burners give up, and wind still costs fuel.

One safety line, plainly. Don't wrap an upright canister in a tight windscreen that traps heat around the fuel. Use a rock or the terrain.

Can it really simmer?

Yes, and this is where it beats nearly everything in its class. OutdoorGearLab scored its simmering 9.0 out of 10, the top score in its table, and says you can make anything from quesadillas to grilled cheese. BIKEPACKING calls the flow control smooth: it takes a full turn before gas streams out.

SOTO credits its Micro Regulator with keeping the output steady across a wide range of temperatures, and BIKEPACKING says that once lit it holds the flame at a steady level, unlike a plain needle valve.

Here's the detail that made me pay attention. BIKEPACKING measured the pot sitting just 9 mm above the burner, much closer than other stoves. Great for efficiency, it says, and a recipe for scorched food if you're not attentive. OutdoorGearLab sees the burner the other way: one of the larger burners on a small canister stove, which spreads heat and leads to fewer scorched spots in the middle of the pan. Both can be true. Big flame, close pot. So stir. A 9 mm gap doesn't forgive a wandering cook.

The piezo, by OutdoorGearLab's account, worked almost every time. BIKEPACKING found it sometimes took a second try in damp cold, and always carries a lighter. So should you.

3.0 oz according to whom?

SOTO prints 3.0 oz, 87 g, with the 4Flex, and 2.3 oz, 67 g, with the optional TriFlex. BIKEPACKING lists 87 g as 3.1 oz. That's the same 87 grams, rounded two ways: 87 g is 3.07 oz. I go with SOTO's printed 3.0. OutdoorGearLab measured 3.8 oz, and 6.8 oz with a light Toaks pot.

BIKEPACKING puts it 10 g, about 0.3 oz, heavier than the PocketRocket 2. For that, you get 3260 W of output, 11,000 BTU in SOTO's figures, against 2430 W for the PocketRocket 2. That's about a third more heat for a third of an ounce.

The cost is bulk. The 4Flex detaches, so it's one more loose part at pack-up. OutdoorGearLab calls it one of its only gripes, and says its testers got quick at taking it on and off. Give it a fixed spot in your pot, and you'll stop losing it in the duff at camp.

3.0 oz according to whom?

What about cold, and what else to look at?

A regulator helps, but it can't change what an upright canister does in the cold. BIKEPACKING says that below about 5°C, 43°F, technique matters more than the stove, and suggests ways like warming the canister. It used the stove through six months of a damp German winter, for coffee stops and overnighters. If you need dependable cooking well below freezing, pick a system built for it. On a cold trip I'd pack a spare can. Cheap insurance.

Fuel math, from SOTO: about 1.5 hours of burn from an 8 oz, 250 g canister. OutdoorGearLab measured about 0.24 oz of fuel per boil in its test.

For alternatives, OutdoorGearLab names the Jetboil Stash if you want an integrated system that stays light. The SOTO Amicus is the simpler, cheaper SOTO. Owners, for what a crowd is worth, are very happy: Amazon shows 4.8 stars from 1,726 ratings as of October 16, 2026. BIKEPACKING adds one more thing I didn't expect to enjoy: it calls the WindMaster shockingly quiet.

Pros

  • Recessed burner: in BIKEPACKING's hairdryer test it boiled where a PocketRocket 2 couldn't
  • Simmering scored 9.0 of 10 by OutdoorGearLab, the top of its table
  • 4Flex takes pots up to 2 L (SOTO), with zero deflection per BIKEPACKING
  • 3.0 oz with 4Flex by SOTO's figure; 4.8 stars from 1,726 Amazon ratings

Cons

  • The removable 4Flex is a loose part and bulky in narrow pots
  • Pot sits 9 mm above the burner, so food scorches if you wander off (BIKEPACKING)
  • Wind still costs fuel: about 15% (OutdoorGearLab) to about double (BIKEPACKING)
  • Cold upright-canister limits apply despite the regulator
