UOG TOP PICK - Soto's WindMaster Stove with 4Flex - Best Regulator Stove for Winter Conditions - We've singled out Soto's WindMaster as one of our top recommendations because it's remarkably light for a feature packed canister gas stove and has a regulated output for winter use. It is so effective in poorer conditions that you don't even need a windshield.

Soto's Windmaster stove uses a micro regulator to maintain output in cold conditions and an internal piezo igniter that can't get damaged. It also has a unique burner head to eliminate performance problems in windy conditions. This set comes withd the 4Flex pot supports.

 SOTO says:

Boil 2 cups of water in under 2-1/2 minutes in strong winds and gusty weather. This well-made stove is able to stand up to harsh conditions.

The Soto WindMaster stove is designed so the pot sits close to the flame, making it more efficient in windy weather. Results in increased efficiency so boil time is quicker and longer. The concave design of the burner head creates the effect of a built-in windscreen. The 4Flex pot support works for a larger pot, but the smaller, TriFlex pot support, is available separately. An efficient stove for whatever size pot your adventure requires.

*NOTE: The WindMaster OD-1RXN which comes with only the 4Flex pot support replaces the previous WindMaster OD-1RXC that came with both the TriFlex and the 4Flex. The stove itself remains exactly the same.

SOTO's Windmaster Stove has all the technology benefits of the Micro Regulator stove and is fitted with a unique burner head that is designed to eliminate performance problems caused by windy conditions.

Its rare that something as ubiquitous as a gas stove gets such a comprehensive design makeover - SOTO have done an impressive job with these stoves by installing technology that really makes a difference. The stove will boil water at the same speed as similar stoves under ambient conditions but upto twice as fast in colder conditions.

This windmaster stove set is supplied with a four pronged pot support for better stability.

A jackpot for outdoor lovers

Well, I have been an outdoor lover for quite long time and been using many different kinds of camping stoves but always look forward for fellow hikers suggestions. That's how I heard about SOTO WindMaster. I am a person who doesn't believe in things that quickly (Typical Engineer who need facts :P) So, it took me almost 3 days to go through different camping stoves available on the market, watching the comparison videos, reading reviews, analysing and then choosing the online store who can ship it promptly. Even though at first the price looks high, but after watching so many videos, I decided it's time to switch to Mr. WindMaster and here I am holding it, delivered from the 'Ultralightoutdoorgear' team, great packaging for such delicate products. Also have ordered Tri Flex with it which is very useful. Super happy and super delighted. Looking forward to enhancing my outdoor experience with this beast :)

Decades of experience in a small package

This has become an undoubtedly popular stove since its release and I understand why. It strikes a perfect balance between reliability, efficiency and weight.

Living in the Northern Hemisphere and hiking inside the arctic circle during the summer I needed something that could handle freezing, wet and windy conditions without failing on me. This is where the WindMaster caught my attationen and proved to be the best stove I've ever owned.

Equipped with a Micro Regulator System allowed me to use the stove in colder temperatures. A stove without a regulator usually loses a considerable amount of its output around 7-8°C. This is because in cold weather the pressure in the gas container decreases which results in a lower output. A regulator keeps the pressure constant and thus the output is the same in colder conditions. This considerably reduces the time how long it takes to boil your water or cook your food. This feature has worked great and has allowed me not to worry about the rapid change in temperature in the mountains. I've used it down to 0°C and it's been working admirably.

To get a reference, Soto has made a comparison between a kitchen with Micro Regulator System and one without and this is what it looks like when comparing the time it takes to boil a liter of water under different temperatures:

Stove with Micro Regulator System: 4:02 minutes
Stove without Micro Regulator System: 3:54 minutes

Stove with Micro Regulator System: 4:01 minutes
Stove without Micro Regulator System: 7:42 minutes

Stove with Micro Regulator System: 4:16 minutes
Stove without Micro Regulator System: 8:16 minutes

It's named WindMaster for a reason. It handles wind better than every top-mounted stove I've used. This is because Soto made the stove in a way that lets the pot sit very close to the burner head itself. The burner head is also concave and with high walls which makes it difficult for the wind to reach the burner head itself. Having used it in strong winds I have to agree with the name, it handles wind very well. There's never been a time that I've wished that I had a dedicated windscreen with me and I don't plan on bringing one with me.

With an output of 3260W you know it's powerful, but for people like me that like to do more than to just boil water in my pot need a way to simmer my food. I'm happy to say that it has sufficient simmer control and lets you warm up your stew without scorching the food. It's not the optimal soultion if you plan on cooking your food every day but it's sufficent for normal use.

As if all of this is wasn't enough, Soto has taken the time to carefully design one of the better Pizo lighters I've encountered. Instead of going on the outside of the burner, Soto has managed to pull the metal piece inside of the burner head where it has a very low profile. The fact that it is made of a flat metal strip instead of a metal wire makes it less likely to break and get caugt on stuff. The low profile also means that it's less likely to not ignite the gas. I find this feature very useful because it's one less item to think about and it's always there in front of you.

Weighing in at 67g using the TriFlex pot support it's lightweight but it's not the lightest stove on the market. This is where the perfect balance between reliability, efficiency and weight comes in. The BSR-3000T might be lighter at 25g but it's missing many useful features and it's considerably less reliable and efficient compared to the WindMaster.

There are two small negatives I could think of with the WindMaster and that's its length and Soto not including the TriFlex pot support anymore. For some reason Soto stopped including the TriFlex and instead offers it as an accessory. I would like to see it included again given that the price of the stove. The other thing is that I usually want to store my cooking kit in my pot but due to the length of stove it makes it hard to stack it together with my spoon and gas canister inside my pot. If you're using a wider pot this is usually not an issue, mostly for taller pots.

The reliability and quality of the WindMaster is a testament of 40 years of experience and should not be taken lightly. It was the highest rated stove on the PCT 2019. It will set you back a pretty penny but I recommend you to not look further because this is the stove you want. You won't regret it.
