Best Merino Wool Pants For Men

Last Updated on March 30, 2025

Wool is a high-quality, functional fabric that enhances comfort, warmth, and performance. There are dozens of brands and thousands of Merino products that act as a soft, protective layer, almost like a second skin. However, it can be surprisingly tricky to find a pair of Merino wool pants that meet all your needs, even with all the gear out there.

And that’s where we come in.

From joggers to dress slacks, we explore the best Merino wool pants on the market. So, make sure to take some notes so you can find the perfect pair of Merino pants for you!

Merino Wool Pants: What To Look For?

Before diving into the top Merino wool pants, we need to look through some of the specs and features we reviewed. Therefore, you can make a more informed decision when searching through each product.

Don’t get too overwhelmed, either. There is a lot of information here (and we don’t expect you to read it unless you really want to). However, just like our Merino wool pants, we suggest you take in the information one leg at a time.

Wool Composition

If you’ve seen our reviews before, you know that we always include wool composition as one of our criteria. The overall fabric composition can say a ton about durability, breathability, comfort, and style. When it comes to Merino pants, many of them have a lower wool composition. This is because the fabric needs to be durable, and wool alone is not the strongest of materials.

So, we have come up with a few rules of thumb. First, the higher the Merino wool percentage, the more comfortable it should feel. However, that doesn’t mean low-wool fabrics are not comfy. Sometimes, it’s necessary to blend with cotton or synthetics to enhance the natural properties of each material.

You get the best benefits from each fabric type with the right blend. But with the wrong mix, some of the disadvantages of each specific material begin to bleed through. In the end, it’s up to you to decide which features are most important to you, but we will always lead you in the right direction.

Material Weight

When we talk about Material weight, we are really equating fabric density. Most brands report their apparel thicknesses in gsm or grams per square meter. Now, for you fellow science nerds, you may have understood that this is a unit of density, not weight. So, two midweight garments that are both 250 gsm may not be the exact same thickness. We understand that this is a difficult concept to grasp, so think of it more as a ‘relative warmth’ category. The higher the gsm, the warmer it is more likely to be.

Fit & Style

When reviewing Merino wool gear, we often focus on the performance properties of the material. But at the end of the day, it doesn’t matter how high-quality the fabric is if the pants don’t fit right! So, we classified the fit into four main categories (as pictured below), so you can better gauge how you will look in each pair of Merino wool pants.

Note: Each brand has its own internal language and fit scale. Each fit classification is our interpretation of each pants’ fit.

Closure Type

We understand this may not be a significant issue, but it’s just a factor that each brand doesn’t usually broadcast. For some pants, the closure type can make or break them. Like, do you really need a button on a pair of sweatpants? And why do your dress slacks have a drawstring on them? Anyways, we tried our best to classify the various Merino pant closure types so you can get a better feel for each product.

Color Options

Depending on where and how you wear your wool pants, you may need a bit of extra style. However, it can sometimes be hard to find the sweats or slacks that match your wardrobe. This is especially true since Merino wool products tend to be drab, neutral colors like black, gray, tan, and navy. While there may not be too many wild color choices on this list, there are many useful, practical options. And, if you like a pair of pants, but don’t see the color you like, let us know! Seriously, we are starting to get some pull out here.

‘True Price’

“Why don’t you include the actual price in your reviews?” We get this question a lot. And we understand that having a dollar value right in front of you may help with your research. However, the prices regularly change, and a simple number should never deter you from exploring further. So we came up with a simple metric, ‘True Price.’

Basically, we use dollar signs to refer to the relative price of the item compared to its competitors. Also, we try to factor in inadvertent costs like dry cleaning, low durability (fewer wears), and even manufacturer guarantees. Therefore, when you finally find your pair of Merino wool pants, you’ll have a better idea of their lifetime value.

Best Overall Men’s Merino Wool Pants

Icebreaker Men’s Merino Shifter Pants

40% Merino (60% LYCRA) | 200 gsm | Slim fit (tapered) | Drawstring | 3 colors | $$$$

Pros: Excellent warmth-to-weight | Multi-pocket design | Stylish tapered fit

Cons: Not great with all outfits | Long-term durability concerns | Expensive

If you’ve been to Merino Wool Gear before, you may think we are biased toward Icebreaker products. However, they often land at the top of our lists due to their high-quality materials and fantastic craftsmanship. And these Icebreaker Shifter Pants are no exception. These well-engineered, minimalist Merino wool pants are a must-have in any eco-wardrobe.

The first thing is first: yes, these look like a simple pair of sweatpants. But that’s actually what makes them so great. There isn’t any need for flash with this type of functionality. The wool/synthetic blend – in combination with the lighter material – provides ample temperature regulation. However, we don’t suggest wearing these pants in rugged environments as the fabric is prone to snagging and tearing.

Still, we love the tapered design of these Merino wool pants. Not only does the slim fit improve versatility, but it also offers enough room for high-movement athletics. And even though they are just ‘sweatpants,’ they still are high-quality enough to be worn with a casual button-down (without looking homeless).

Finally, we know that the Icebreaker Shifter Pants can be a bit pricey. Yet, with manufacturing guarantees, extra comfort, and a chic all-around look, we feel the price tag is worth it! Moreover, most of the Merino wool pants we’ll review today will cost you a pretty penny.

Best Wool Pant: Runner-Up

Wool & Prince Denim Jean

31% Merino wool denim (69% cotton) | 315 gsm | Slim fit | Button | Dark Indigo | $$$$

Pros: Functional features | Fashionable, versatile style | One of the only Merino jeans out there

Cons: Not great for shorter people | Fabric inconsistencies | Sizing availability

Buckle up because we’re diving into the world of Merino wool jeans, a rare breed indeed. Now, you might be thinking, “Merino wool jeans? Isn’t that an oxymoron?” Well, it practically is. But fear not, because Wool & Prince has done the seemingly impossible and crafted a pair of Merino wool jeans that are not only real but might just become your new wardrobe staples.

So, what makes these Wool & Prince Denim Jeans so special? Let’s start with the magic ingredient: Merino wool. Who knew you could get all that cozy goodness in a pair of jeans? These jeans are like a dream come true for those who crave the classic denim look but can’t stand the usual stiff, scratchy material.

Now, before we get carried away singing praises, there are a couple of things to keep in mind. Finding the perfect fit might be a bit of a challenge. Sizing can be a little inconsistent according to some reviews, and these jeans are currently only available in a slim fit. Also, a few folks have mentioned that the material might be prone to ripping or tearing after some wear.

But here’s the thing: with all things considered, the Wool & Prince Denim Jeans are absolutely worth the investment. They offer an unmatched level of comfort and breathability in a classic denim design. Sure, you might need to do a little size-hunting. But for the chance to experience pure Merino wool comfort in a pair of jeans? We say sign us up! These are definitely a unique wardrobe upgrade worth checking out.

Best Everyday Merino Wool Pants

Ridge Merino Hyde Jogger

100% Merino wool terry | 275 gsm | Tapered fit | Drawstring | 4 colors | $$$

Pros: Top-of-the-line comfort | Casual style | Warm yet breathable

Cons: Hardware durability | Fabric longevity concerns | Expensive for sweatpants

Alright, listen up if you’re searching for the ultimate comfy Merino wool joggers. These Ridge Merino Hyde Joggers are no joke – they might just become your everyday go-to pants. Why? Because once you experience the unbelievable comfort, you won’t want to take them off!

Whether chilling at home, hitting the gym, or running errands around town, the Hyde Joggers will keep you feeling stylish and comfortable all day. The tapered-leg design ensures a flattering fit that complements any outfit, and trust us, that goes for everything in the Ridge Merino collection.

But Ridge Merino didn’t just stop at looks. They crafted these joggers with 100% Merino wool Terry knit fabric, the softest, plushest material you can imagine. It’s like a hug for your legs! And with thoughtful features like flatlock seams to prevent chafing and hand-warmer pockets, pure comfort is guaranteed no matter what your day throws your way.

In short, if you’re looking for a dependable, stylish, and ultra-comfortable pair of Merino wool joggers, look no further than the Ridge Merino Hyde Joggers. We’re not just saying this—we’re living proof! These joggers are absolutely worth the investment.

Best Merino Wool Travel Pants

Woolly Longhaul Pants

75% Merino (21% bamboo & 4% elastane) | 450 gsm | Regular fit | Button | 4 colors | $$$

Pros: Versatile, functional construction | Lightweight, airy fabric | Packs small

Cons: Cut not suited for everyone | Pilling experienced | Sizing inconsistencies

Woolly has an exciting take on Merino wool. While many outdoor brands focus on high-performing alpine wear, Woolly understands that you can’t spend every day in the woods. However, they transfer the power of Merino outdoor clothing to daily life with their Merino Foundation Wear. And the Woolly Longhaul Pant was one of their flagship pieces of gear.

Before we get into the specs, we’d love to share how these pants actually came to be. Woolly launched a Kickstarter campaign back in 2018 that raised over $200,000 to fund the production of these pants. It worked so well that they created two more Kickstarter campaigns for their all-Merino jackets.

Anyways, their Longhaul pants are designed for the on-the-go traveler. The heavyweight 450-gsm fabric offers warmth while managing moisture well. Moreover, there is even a hidden, anti-theft zipper pocket in the back! The material itself is more professional-looking than other Merino alternatives. Therefore, you can wear them with more variety of outfits when you’re on the go.

However, the only real gripe we (specifically me) have is that regular cut doesn’t look great for shorter people. It’s a bit boxy, and since the sizing runs large, you have to get them hemmed.  Still, the Woolly Longhaul Pants are our go-to for one-bag trips, as they pack small and weigh under a pound. And, we get to experience the comfort of Merino wool even in the discomfort of an airport terminal!

Most Comfortable Merino Wool Pants

Ibex Nomad Joggers

95% Merino (5% elastane) | 210 gsm | Relaxed fit | Interior Drawstring | 3 colors | $$$$

Pros: Superior comfort | Functional fit | Useful pocket design

Cons: No choices for inseam length | Limited versatility

If you’re looking for a comfy pair of Merino wool pants, you’re in luck! We think the Ibex Noman Tranquil Joggers are the coziest pair on the market! The 95% blend of Merino wool provides a sensational next-to-skin feel. Moreover, the fabric itself is not the only reason we love these comfy Merino wool pants. Ibex crafted the design of these joggers with the utmost precision. The pockets are functional, the taper is near-perfect, and plenty of room for movement with their self-titled ‘relaxed’ fit. Although, we would call them more of a regular-tapered fit as they are not very baggy.

Ibex notes in their sizing charts that for a medium & large, the inseam is 31-32″. Although, we have noticed that the inseam is a bit long, especially for shorter people. Again, it’s not a dealbreaker for us, but it would be nice if they offered more variety of inseam lengths.

In summary, the Ibex Men’s Nomad Joggers will keep you comfy around the house or on the go. They truly are perfect for any nomad who values comfort on the road!

Best Merino Wool Dress Pants

Ministry of Supply Velocity Dress Pant

49% Merino (49% polyester & 2% polyurethane) | Lightweight | Slim & Regular fit | Hook & Button | Black | $$$$$

Pros: Professional, classic style | At-work performance | Matching suit jacket

Cons: Minimal stretch | May need to hem | High price tag

As we mentioned before, Merino wool is a solid pants fabric, all the way from the gym to the office. And in our opinion, the best pair of Merino wool dress slacks is none other than the Ministry of Supply Velocity Pant. They are an ideal combination of comfort and professionalism that we don’t often see with other wool pants.

The premium Merino fabric is blended with polyester for a formal yet stylish look. Moreover, with Merino’s natural wrinkle resistance, you’ll always look good at work. Although, we do have a few gripes about these pants that we’d like to note. Ministry of Supply says that the fabric is a “4-way stretch woven,” yet there isn’t much stretch to these pants. And, while the non-wool Velocity pant is available in several colors, the Merino version only comes in black. Plus, they are a bit expensive, but what do you expect from a luxury piece of Merino wool gear?

Overall, suppose you need a solid pair of black pants for a wedding, work, or just a night on the town. In that case, you can’t go wrong with these Velocity Merino Pants. As the Ministry of Supply would say, it’s a perfect blend of ‘comfort & convenience.’

Best Merino Wool Base Layer Pants

Smartwool Merino 250 Bottoms

100% Merino | 250 gsm | Athletic fit | Elastic band | 6 colors | $$$

Pros: ‘Sweet spot’ temperature regulation | Trusted Smartwool brand | Perfect base layer

Cons: Unflattering standalone piece | Not quick-drying | May stretch with improper care

Of course, these Smartwool 250 Bottoms aren’t your typical pair of Merino wool pants. We would classify them as base layers – something to be worn underneath something else. Still, these are the best thermal underwear on the market. And if you want to wear them as pants, you do you.

The fit itself is slim, with enough room for movement, but not overly baggy that you can’t layer overtop. Plus, Smartwool has recently updated its base layer design to be more performance-oriented. Overall, it’s a minimalist, simple design that focuses more on functionality as opposed to aesthetics. 

Anyways, these seemingly-basic wool ‘pants’ are actually jam-packed with features. The midweight, 100% Merino wool construction provides plenty of warmth, breathability, and durability. Although, if you’re planning on getting wet, you may want to look elsewhere for Merino wool long underwear. These aren’t the most quick-drying pair of the bunch.

To sum up, if you need a base layer, you can’t go wrong with Smartwool. In fact, even in the transitional seasons, we wear them as pajamas. Although in the summer, we opt for the lighter 150 gsm version. Either way, check out a pair of Smartwool Base Layer Bottoms today!

Best Wool Hunting Pants

Big Bill Merino Wool Hunting Pants

80% Merino (20% nylon) | Heavyweight | Regular Fit | Button | Hunter green | $$$$

Pros: Improved durability | Interior suspender buttons | Accessible cargo pockets

Cons: Not a lot of stretch | Sizing runs large | Dry clean only

Rugged and comfy? We know you don’t see those descriptive terms together very often. Yet, the Big Bil Merino wool cargo pants are just that. These heavy-duty, 80% Merino pants are for outdoor comfort, especially for extended periods. Combined with the olive drab color, they actually make a solid pair of hunting pants. 

Note: While we have deemed these Merino wool cargo pants for hunting, they can be used for all sorts of outdoor activities. In fact, they also make the perfect outdoor work pant – especially when you have to rake the leaves in near-freezing temperatures!

The outside texture of these pants is more felted than many of the other options. While this enhances your comfort levels, it’s also the reason that Big Bill recommends that they only are dry cleaned. So, make sure you factor in that cost when making your decision.

Still, we can’t think of a more rugged pair of Merino pants. And yes, they don’t stretch as much as we would like, but the fabric loosens up with use. Trust us when we say that you have to give them a shot (pun obviously intended).

Best Merino Wool Hiking Pants

Icebreaker Men’s Merino Hike Pants

59% Merino (41% cotton) | Midweight | Regular fit | Button | 2 colors | $$$$

Pros: Durable wool-cotton canvas | Enhanced hiking features | Functional pockets

Cons: Fit discrepancies | Limited color selection | Length may be too short for some

If we are out hiking, we typically wear Merino wool shorts. However, when there is a lot of brush and the potential for ticks, we wear pants on the trail. And our favorite pair of Merino wool hiking pants are the Icebreaker Merino Hike Pants. They are a solid blend of comfort, durability, and protection, three must-have properties when exploring nature.

As wool lovers, we have to talk about the material first. The wool-cotton canvas feels soft and luxurious, yet is extremely durable. That way, you won’t have to worry about snagging or tearing the fabric on any loose branches. However, we think that Icebreaker could use a higher ratio of wool in these pants and still get the same enhanced properties.

Moreover, when you’re hiking, you want to ensure there is no discomfort irritation in terms of how your pants fit. Icebreaker uses a gusseted crotch for mobility and ‘articulated knee seams‘ so that the fabric doesn’t stretch out over time. And while we don’t suggest wearing them in freezing temps for extended periods, these Merino Hike pants perform well in cooler climates.

Lastly, you know you can trust products from Icebreaker. They are one of the most well-established Merino wool brands, and this is even their second entry on our list. So, grab a pair for your next backpacking trip now!
