Gear Review: SOTO Amicus and WindMaster Backpacking Stoves

SOTO Ultralight Backpacking Stove Review Amicus Windmaster

The SOTO Amicus ultralight backpacking stove boils 1L of water in under 5 minutes. 

SOTO Outdoors entered the world market in 2010 and, pun totally intended, the ultralight stove brand is on fire. The Japanese stoves have racked up multiple industry awards, with accolades ranging from Backpacker Magazine's Editor's Choice award to The Gear Institute naming it Best in Class.

The SOTO Amicus is the brand’s first entry-level backpacking stove and, as the name implies, really is a ‘friend of the court’. Reliable, lightweight and budget friendly, it was awarded Outdoor Gear Lab’s “2022 Best Buy” award. 

The SOTO WindMaster, which received Outdoor Gear Lab’s “2022 Editor’s Choice” designation, features burner units that are slightly recessed below a protective lip, offering a shield from the wind. In addition, the cookpot sits closer to the flame than its Amicus rival, making it even more efficient in blustery conditions.

Pros of SOTO Amicus and WindMaster Backpacking Stoves

Lightweight and Compact

They’re so simple! The Amicus and WindMaster are equally minimalistic, extremely lightweight and pack down to a remarkably small size.

Fuel Compatibility

It’s easy to love a stove that works with all standard isobutane canisters.

Wind Resistant

SOTO Outdoors engineered both stoves to have a raised ledge at the crown of the burner heads to stave off the wind.  It’s no surprise the WindMaster has a larger burner and a more prominent windshield ideal for more extreme weather conditions. Neither stove had any problems with the 5 mph Chinook wind gusts encountered during product testing.

Piezo Igniters

The Amicus and WindMaster stoves utilize identical Piezo igniters and were extremely easy to fire up with the push of a button. No priming, lighters or matches needed. Piezo igniters have been known to lose their reliability at higher elevations, but the ease and convenience of the igniter at 3,100’ elevation got a solid thumbs up from me.

Long Control Wire

The Amicus and WindMaster are both equipped with long control wires making it easy to reach and adjust the flame without burning your fingers. Another bonus of the control wire is … control! Without the regulator, a stove doesn’t do much more than boil water.  SOTO’s regulators allow for simmering abilities so you can add some versatility to your backcountry meals.

Both the SOTO Amicus and Windmaster backpacking stoves are significant upgrades from the MSR WhisperLite days of yore.

Cons of the Stoves

Pot Supports

When compared to the WindMaster, the Amicus’ spring-loaded pot supports look short, tiny and appear less stable. They performed adequately on my 2-liter cookpot, but my confidence in the pot’s stability was lacking. A 1-liter cookpot would have seemed more fitting with this setup.

The WindMaster’s much longer and more robust stabilizers definitely enhanced my trust in the stove system. However, as much as I loved the integrity of the WindMaster’s 4Plex pot supports, I didn’t love that they are a separate piece, requiring installation and removal each and every time. They are easy enough to assemble; it’s just one more piece of gear to have to manage. It’d be a sad day in the backcountry if they were lost or damaged, rendering the WindMaster useless. 

Fuel Canisters

These ultralight stoves necessitate purchasing one-time-use fuel canisters. While extremely convenient, and fairly ubiquitous, there are some downsides too: it can be hard to know exactly how much fuel is left in a canister; it's another thing that needs to be bought and carried; and recycling them isn't always the easiest, meaning more often than not, empty canisters end up in a landfill.


Good to Know

  • If the Piezo ignitors are being weird, you can always just use a lighter (or mash the igntor button a bunch until it works ; )

  • SOTO certainly isn't the only brand making canister backpacking stoves. Other popular options include: the MSR Pocket Rocket (also available at GGG!) and the BRS-3000T.

The SOTO Amicus is a reliable, lightweight, budget friendly backpacking stove.

SOTO Outdoors offers impressively lightweight and high-quality backpacking stoves for an affordable price. The Amicus and WindMaster were equally simple to unbox and fire up. They aren’t the fastest available stoves, but being able to boil water in under five windy minutes is still pretty darn slick.

If you see yourself adventuring in cold, wet and windy conditions, the SOTO WindMaster would be worth the extra cost and the additional 0.4 ounces in weight. However, if you’re just looking for a reliable, unfussy and lightweight backpacking stove to get the job done, the SOTO Amicus is your friend.

Gear reviews




I own both stoves and I do notice that the igniter on the windmaster is more finicky about where you have the valve opened up to when you try to light it. I usually open it up to a half turn bellow full blast and let it rip and it lights every time. No issues with excessive burn off doing it that way either. If you try to just let a trickle of gas come out and light it the igniter on my example struggles. Once I figured that out it has been smooth sailing ever since. The amicus is also a nice stove, I purchased the amicus first with the cook pot set because the deal was too ridiculous to pass up and honestly I probably didn’t need the windmaster because the amicus gets the job done but gear junky I can be.

Anyway in my testing at 5000 ft altitude, where I live, both stoves performed more or less the same as far as how much fuel they consume but the windmaster can boil around 750ml in under 3 minutes while the amicus spends a little longer getting it done … closer to 3 1/2 minutes. as the name implies the Windmaster is great in windy conditions but the amicus is no slouch either.

Just to touch on the igniter issue again I carry a small fire steel as a backup anyway just in case I ever have igniter issues or need to make a fire. I would say it’s a good practice not to rely on built in ignition with any stove so if you are weight conscious that could be a reason to get one of the amicus models without the Piezo igniter and just carry a bic or fire steel.

I’ve never had a problem with the piezo lighter on my 5 year old Windmaster at altitudes up to 11,00’. Must be luck.

I really like my Windmaster, but I can confirm that the piezo electric lighter is unreliable at 9,000 feet or higher. Carry a Bic lighter!
