Merino wool products have evolved a lot over the past decade. The diversity in designs, layers, and accessories is stunning.

Unfortunately, this also means a lot of copycat brands exist. They’re hit or miss, and clothing that frays in a few months isn’t anyone’s cup of tea.

In this article, I’ll review Meriwool: a young merino wool company and a better ‘new gen’ brand. I’ll compare it to two old schoolers, Smartwool and Minus33.

In a hurry? Here’s a quick overview of my Meriwool vs Smartwool vs Minus33 recommendations.

➥ MERIWOOL has a great price-to-quality ratio in the following categories
–

• Smaller accessories: More specifically, the fantastic beanies or comfy neck gaiters.
  –
• Midweight base layers if you’re on a budget: This one is for men, the women’s option is here.

➥ SMARTWOOL uses denser, less itchy wool than Meriwool. Lineups that fully utilize this are:
–

• Leggings: This women’s base-layer pair has been the choice for women around me. The men’s leggings are great too.
  –
• Base layers: Smartwool 250 crews (check example) in particular are the best in their weight category.
  –
• Casual socks: The Everyday Margarita are unisex, have great designs, and are the most comfortable socks I’ve laid a foot in.

I’ll be honest with you. For some smaller pieces of clothing like scarves, me and my SO actually knit our own!

We’ve tried a lot of merino yarn. None of it would match either Meriwool or Smartwool when it comes to actual layers, though. It also takes a lot of time:

➥ MINUS33 comes last, but not least on our list.

Price-wise, the brand stands right between Meriwool and Smartwool. Several products I feel deserve recommendations are:
–

• Casual T-shirts: the Algonquin short sleeve crew is affordable, perfect for spring to autumn activities, and fits better than competitors.
  –
• Hiking socks: the Day Hikers are breathable, comfy, and come with full cushioning for mountain trail action.
  –
• Ultra warm layers for harsh weather: the Yukon Expedition crew is an industry leader. As far as leggings for freezing temperatures go, the Katmai leggings are unbeatable.

Now that I got the recommendations out of my system, let’s continue with some more insights on the merino wool lineups from these three brands.

It’s obvious that all three brands are moisture-wicking, eco-friendly, and very comfy. We’ll be taking a look at some finer print differences between them.

I mentioned how Meriwool isn’t your typical new generation merino wool brand. What does that actually mean?

Well, a lot of these newcomers utilize cheap production. Many don’t source proper materials (read: merino from New Zealand or Australia). Or, they feature a reduced percentage of merino wool (<60%) in the fabric materials.

While Meriwool undercuts its competitors in terms of price, it doesn’t sacrifice merino fundamentals. A few examples would be:

• Meriwool clothes don’t pill faster during washes (a lot of newer brands do that).
• The clothing uses properly sourced merino wool which accounts for 80-100% of the total fabric.

So what’s the tradeoff, then? Why compared to Smartwool, Meriwool is sometimes almost double the cheaper?

Smartwool uses denser merino wool in its clothing. Meriwool relies on different thread materials, which makes its clothing not as warm and slightly itchier.

You can see Meriwool long sleeves using fine or superfine wool:

To some people, those initial few weeks of merino wool becoming less itchy are a big deal. And it’s no secret that Smartwool products are especially consumer-friendly in this regard.

The denser merino wool Smartwool uses also means you’ll be better equipped in the colder months.

As a rule of thumb, Meriwool is great for early spring to late autumn. If you live somewhere with milder winters, their merino wool clothes would fare well too.

As far as harsher winters go, though, Smartwool’s base layers (check some unconventional colors), midweight crews or leggings will perform better in colder areas.

Last but not least, Smartwool products feature improved stitching. Their seams are also better designed and thus slightly more convenient/durable.

The finer merino wool in Meriwool products has one big benefit, though: it dries quicker and is generally more breathable.

If you’re looking for some cycling or hiking in a milder climate, you’d appreciate their approach to merino wool manufacture.

In the beginning, I pointed out how price-wise, Minus33 generally positions itself between Meriwool and Smartwool.

In some segments, this has a clear reason. One such example is the brand’s midweight base layer – the Chocorua crew.

While more premium than Meriwool and just a notch below Smartwool, it features a reduced density. The other two brands have their crews at 250g/m2, while the Minus33 is 235g/m2.

This might look like a small detail, but it still cuts down on manufacturing costs and helps the brand snuggle itself between its competitors.

The equivalent to the Chocorua for women is the Ossipee midweight crew:

The reason I mentioned heavyweight is Minus33 products’ forte, though.

The brand’s name points out a very concrete specialization: expedition-grade gear. If you noticed, my recommendations for their products were all centered around hiking or general extreme weather outdoor activities.

Minus33 might take grams per square meter off their base layers, but they put them all back when it comes to heavyweight layering. As an example, usually, you see merino wool outer shells or jackets going at 380g/m2.

Both the Katmai leggings and the trademark classic, the Yukon Crew feature a 400g/m2 interlock knit construction. The design and density make them a superior choice if you’re set on conquering icy landscapes or freezing conditions.

Furthermore, there’s one additional benefit to how Minus33 approaches their merino wool clothing.

The size fitting is generally snugglier and more ‘as expected’ than most industry brands, Smartwool and Meriwool included.

If you look at the product lineup of all three brands, you’d notice terms like microns, g/m2, layering, etc.

The way merino wool works is slightly different than your typical clothes. Its moisture-wicking qualities, as well as the retention of heat makes merino a very versatile material for layering and ‘composing’ a harsh weather-proof strategy.

Generally, there are three main types of layers:

• Base layer
• Midweight (mid) layer
• Outer shell (heavy) layer

Some think of the midweight layer as an ‘insulating’ layer too.

These main types of layers correspond to specific densities – that would be the grams per square meter. Generally, the gist of it is:

• Base layers range from 150 g/m2 all the way to 200g/m2.
• Midweight layers range from 230-260g/m2. Most mid-merino wool crews you’ll see are 250g/m2.
• Outer shells or merino wool jackets range between 360-400g/m2.

Meriwool themselves have a very neat short video on layering if you’ll be packing for an extended trip somewhere up the snowy peaks.

As far as Smartwool goes, I have a guide on their 150 and 250 layers.

When it comes to other budget brands, I’ve also discussed Merino.Tech here. Interestingly enough, they start their base layers at 165g/m2, instead of the traditional 150g/m2.

Going beyond layer classifications:

An additional detail is the so-called micron as a measuring unit. The micron is basically a measure of whether the merino wool piece of clothing is soft or pricklier.

At its core, merino wool is simply a combination of many fibers put together. When the fibers range between 15 and 19 microns, they are considered anywhere from fine to super fine. This makes them slightly softer on your skin.

In comparison, when the merino goes above 30 microns, it’ll feel coarser. You might notice it prickling on your skin and it’ll definitely feel a bit itchier.

As I said, I tend to be a bit verbose when it comes to things I’m hyped about. Hopefully, that wasn’t too long of a read and you could gain some knowledge on the difference between Meriwool, Smartwool, and Minus33.

I’m definitely of the mindset that you don’t have to always overpay for merino wool clothing.

In light of this, I reiterate that in my opinion, Meriwool is a total bargain for things like cheaper (but quality!) merino wool accessories.

When it comes to higher-end requirements, though, I believe both Smartwool and Minus33 warrant their higher price tag.

There’s a fun fact, by the way. I haven’t spoken of another competitor, Icebreaker. A few years ago, Smartwool and Icebreaker were a fierce competition with each other under different companies.

Now they’re both owned by the same enterprise – VF Corporation after it acquired Icebreaker in 2018. They own quite a bit of outdoor brands (The North Face, Napapijiri, Timberland). At the same time, they spun off their workwear division into a corporation called Kontoor. I’ve written about them in my Wrangler vs Rustler jeans article, as Kontoor owns both brands.

What a rollercoaster of apparel events, huh?
