We aren’t making any affiliate money from this post yet, but please be sure to take a look at our Editorial Guidelines to understand our ethos for sustainable products.

Merino Wool is one of those fabrics that really caught my attention around the Summer of 2019.

I was researching sustainable fabrics,

you know,

things that were better than Cotton – and I came across Wool.

Weird… Wool sounds… HOTTTTT….. and iiitchy.” I laughingly said to myself as i tabbed open 4 or 5 articles to begin reading.

As I read, researching Merino Wool further, I discovered some surprisingly beneficial reasons to wear it (in the Summer of all seasons.).

But the strangest thing was…

I became a REAL fan when I started wearing Merino Wool Underwear.

As a late comer to wearing ‘Wool’, being from SoCal and all, I never really understood why anyone would wear wool in the summer. Let alone wool underwear.

After reading about all of the benefits I started trying a couple different brands tees, and underwear.

The thing about the underwear for me personally was the fact that it never smells… like ever. Even after the longest hikes, Leg-day sessions at the gym, runs and sprints in 95+ degree weather, or just day to day life.

Not only that, Merino dries ridiculously quick, but manages to stay light through the craziest workouts. I’ll go into more detail about how this actually happens as we move along.

We’ll make sure to answer “Why Merino Wool anyway?”

Trust me, I was in your cotton underwear not too long ago. But buckle up, because we’re about to embark on an adventure together, Un**-Mulesing** (; the world of Merino Wool.

And let me tell you, it makes way more sense than you’d think.

Secrets? Yep, Merino Wool has them, and I’ll spill them all. How can something as simple as merino wool transform your daily comfort, workouts, and even those unbearable hot summer days? It’s not magic, but Science.

Ethics? We’re going there too. You’ll want to know where this wonder wool comes from, how the sheep are treated, and what makes some brands stand out from the rest in the ethics department. It’s good stuff to know, especially if you’re trying to make choices that align with your values.

Appeal? Yeah… that’s exactly why i’m writing this! We’ll explore why Merino Wool has become the go-to choice for those who’ve discovered its awesomeness (myself included). From the finest underwear to the coziest winter wear, Merino’s got something for everyone.

So stretch out your back, grab a matcha, get ready to put some Merino Wool undies in your cart, and let’s get straight into it.

What is Merino Wool Underwear and How is it Made?

Merino Wool is like the celebrity cousin in the wool family. It comes from Merino sheep, an extraordinary breed known for their incredibly fine and soft wool fibers. Now, I know what you might be thinking: “Wool is wool, right?” Not this wool, nope! Here’s why – Merino Wool’s fibers are so fine that they feel silky smooth against your skin.(inset Merino wool vs wool photo) Unlike regular wool, which is definitely itchy, hot, scratchy, and uncomfortable most times of the year, Merino gives you nothing but pure comfort. It’s like a gentle hug in underwear form!

From Sheep to Chic: Turning Raw Merino Wool into Underwear

Alright, so you’ve got these fantastic sheep with their top-notch wool.

How does that turn into something you’d want to wear, especially as underwear?

It’s an intriguing process.

First, the wool gets sheared from the sheep (there are a couple ways that this happens by the way which we’ll get into next).
Then, it goes through a cleaning process called scouring.

We’re talking about taking raw, unbathed wool and transforming it into something clean and pure.

Next up, it’s spun into yarn, woven into fabric, and finally crafted into those super comfortable underwear you can’t get enough of.

It’s art, science, and a touch of magic all rolled into one.

Ethics and Mulesing: What You Need to Know

H4: Ethics and Mulesing: What You Need to Know

Now, here’s a topic that’s as important as it is sensitive: ethics.

In the wool world, one word you’ll come across is “mulesing.”

It’s a practice that’s done to some Merino sheep to prevent a condition called flystrike (Flystrike in sheep is a myiasis condition, in which domestic sheep are infected by one of several species of flies which are external parasites of sheep.).

But, it’s controversial because it can be painful for the sheep.

That’s where the terms Mulesed and Non-mulesed come into play.

***Mulesed Merino Wool*** comes from sheep that have undergone this procedure.

Some folks are okay with that, while others prefer to avoid it.

We personally choose to avoid working with brands that mulese because it’s harmful to the sheep, and we don’t want that.

Non-Mulesed Merino Wool means that the sheep haven’t gone through this practice, and many consider it a more humane option.

In fact, 91.8% of wool producers believe animal welfare is improved by not mulesing sheep.

This should be the standard we uphold as we go on respecting the earth and the animals on it.

By purchasing from brands who uphold this standard, we force old practices out by showing there is no demand for that kind of product anymore.

That’s the best way to make our voices heard.

We make sure the brands that we promote here follow at least one, or all of these:

RWS (Responsible Wool Standards)

B-Corp Certification’s

ZQ Accreditation

We will go into more detail in the Certification portion.

Why Merino Underwear is Better Than Other Materials:

First and foremost: comfort.

You know how some fabrics stick to you like a bad habit when you sweat?

Not Merino! It’s like the Bounty paper towel of fabrics with its moisture-wicking abilities, pulling that sweat away from your skin.

Merino is thermoregulating – meaning it knows how to play it cool in the heat and cozy in the cold, regulating your temperature like a personal thermostat.

Believe that once you wear Merino Wool Underwear, you’ll wonder how you ever settled for anything less.

Now, sustainability. Merino Wool isn’t just about feeling good; it’s about being good to the planet too.

It’s a sustainable choice, you see, conserving water like it’s the only natural resource every living being needs to live on this planet.

Mainly because if you wear it how it’s supposed to be worn, you won’t need to wash it after every wear. You can actually wear the same underwear all week…

Meaning you can do 1/7th the amount of laundry in a year…

And here’s the cherry on top: once you’ve worn it to bits, it doesn’t just sit in a landfill.

Nope, it biodegrades, returning to Mother Earth.

So, if you’re looking for underwear that loves you and the planet, Merino’s the way to go.

But hey, let’s not stop there.

Merino’s got another ace up its sleeve – versatility.

It’s like the Swiss army knife of fabrics, equally at home in the scorching summer or the freezing winter. How cool is that? Speaking of cool, have you heard of mens wool long underwear?

It’s Merino magic for your legs, keeping you warm when it’s cold, and cool when it’s hot.

Honestly, weather just becomes irrelevant to you when you’ve got Merino.

And there are products tailored to every single aspect.

Merino Wool Fact:

Merino Wool comes back year after year…

That’s right, Merino sheep grow a new fleece every year, making wool a renewable resource.

But what does “renewable” mean?

Well, it means that we can use it over and over without running out, or harming the planet. The sheep grow the wool, we utilize it, and then it grows back again.

It’s nature’s way of recycling!

So why does this matter to you? Because when you choose Merino Wool, you’re supporting something natural and never-ending. It’s a choice that helps the planet and makes you feel good, too.

Every time you wear Merino Wool, you’re part of something bigger.

It’s an ideal fabric for underwear because it can regulate temperature, keeping you cool in the summer and warm in the winter. Plus, its natural antibacterial properties minimize odors, making it a great choice for comfort and hygiene.

Are merino wool underwear worth it?

Although the initial cost may be higher compared to regular underwear, the long-lasting quality, ethical sourcing, and unique comfort features make it a valuable investment for those prioritizing sustainability and well-being.

What is a disadvantage of using merino wool?

  • While Merino Wool offers many advantages, it might not suit everyone. Some individuals might find it more expensive than other materials. Additionally, care must be taken while washing, as it can shrink if not handled properly. Lastly, from an ethical standpoint, some Merino Wool is obtained through mulesing, so it’s crucial to choose brands that use non-mulesed or ethically sourced wool.

What is the best wool for underwear?

  • Merino Wool is often considered the best wool underwear. Its fine fibers make it softer against the skin compared to other wool types. With its moisture-wicking, temperature-regulating, and antibacterial qualities, Merino Wool provides unparalleled comfort and functionality as an underwear fabric.

How often should you wash merino wool underwear?

  • Merino Wool doesn’t need to be washed as frequently as other fabrics, thanks to its natural odor resistance. It’s typically sufficient to wash them after every third or fourth wear, or even less if worn briefly. However, always follow the care instructions on the label, as some brands may have specific washing guidelines.

  • Wool underwear, especially Merino Wool, is chosen for its unique combination of comfort, functionality, and sustainability. It offers temperature regulation, moisture management, and softness, making it suitable for various weather conditions.

Important Considerations and Certifications To Look For When Choosing a Merino Wool Brand to Support:

RWS (Responsible Wool Standard): RWS ensures that the wool comes from happy, healthy sheep and that the land they graze on is treated right. It’s a promise that you’re wearing something that cares for our four-legged friends and Mother Nature.

B-Corp Certification’s: “There is no planet B”: B-Corp Certification. Imagine a group of companies coming together and saying, “We want to make the world better, more ethical, and put people over profit.” That’s what this is! It’s about more than just profits; it’s about social responsibility, taking care of employees, the community, and the environment. Wearing a brand with this certification is like giving a high-five to positive change. Supporting companies with B-Corp certs help change the industry of fast fashion and garbage conditions for workers.

ZQ Accreditation: Last but not least, there’s ZQ Accreditation. This isn’t just a badge; it’s a commitment to excellence. It’s about quality, sustainability, and making sure wool is top-notch, without hurting or harming the sheep!

From ethical animal welfare to environmental protection, it’s the whole package. If you see a Merino Wool product with ZQ Accreditation, you know you’re getting the best of the best, the crème de la crème.

See how these certifications aren’t just logos or stamps?

They’re like a story of who made your clothes and how they did it.

Next time you’re shopping for Merino Wool, remember these, and you’ll not only look good but feel good about what you’re wearing.

Other Eco-Friendly Materials and Fabrics to Look Into:

Other Eco-Friendly Materials and Fabrics to Look Into:

You’re probably wearing cotton right now, but have you met its cooler cousin, Organic Cotton? Unlike normal cotton, it grows up without pesticides, herbicides, or synthetic fertilizers.

It’s softer, and better fitting than normal cotton infused with an eco-friendly twist, just like Merino Wool, but it feels a bit different to the touch.

Hemp: Now, this is a powerhouse!

Hemp’s been around for ages, but it’s making a comeback in the sustainable scene.

It grows fast, needs very little water, and turns into strong, durable fabric.

Compared to Merino Wool, it’s a bit tougher but just as dedicated to saving our planet.

Bamboo: Silky smooth and super sustainable, that’s Bamboo.

It grows like a weed (it is grass afterall), and when turned into fabric, it’s soft and breathable.

While Merino Wool excels in temperature regulation, Bamboo is all about that luxurious feel.

Tencel/Lyocell: Ever worn wood? Well, sort of.

Tencel/Lyocell comes from wood pulp, and it’s a master of eco-friendliness.

It’s produced using a closed-loop process, meaning nearly all the chemicals used are recycled.

Soft, biodegradable, and sustainable, it’s a solid alternative to Merino Wool if you’re looking for something a tad different.

So here’s the thing: Merino Wool is awesome, and I’m clearly a fan.

But if you’re ever in the mood to mix things up, these alternatives are like the eco-friendly Avengers, each with their superpowers.

From Organic Cotton’s pure nature to Hemp’s rugged charm, Bamboo’s elegant touch, and Tencel’s innovation, they’re all worth a try.

Allow me to wrap this all up and put a cozy Merino bow on it:

A promise to our planet and to the cute sheep that make it all possible.
