What is Merino?

Merino wool comes from the Merino sheep which produce a wool which is durable and soft. Typically these sheep are from New Zealand, however there are more and more of these farms springing up around the globe. Typically, these sheep graze in the low lying valleys of mountains, as well as climb the mountains, and thus the wool they grow must be able to help them survive those vastly different climates.

To many, merino wool is a bit of a super fabric.

The Benefits

The benefits of merino wool are huge, and hard to believe when you first read about them. The first is thermal regulation, which is a fancy way of saying that it will keep you warm when it’s cold, and cool when it is warm. The second is anti-odor: it naturally resists odor. The last is water repellence: it has natural ability to repel water (due to the natural oils in the fibers), as a lightly coated DWR garment might, and thus helps with stain resistance.

Thermal Regulation

Thermal regulation is a massive factor of comfort throughout the day — it’s why people often buy specific clothing for the gym, because that clothing is better at thermal regulation than their cotton t-shirts.

Merino is awesome at keeping your body comfortable in two ways. Moisture wicking — as you sweat, the merino will absorb that sweat, pulling it away from your body and towards the fabric’s surface where it will dry quickly. Insulation — merino can help your body regulate temperature because the natural shape of the fiber allows it to trap a lot of air. This makes it act as an insulating layer, just like the fiberglass insulation in your house. This insulating effect helps keep you warm in the cold and cool in the heat.


Lastly, merino wool is anti-odor, and we specifically use anti-odor instead of the more common ”anti-bacterial” or “anti-microbial” because those are both technically questionable. The gist of it is this: merino wool tends to not trap odors for a variety of reasons, the most accepted that the absorptive power of the fiber traps moisture, giving no place for odor causing bacteria to grow. That means: body odor, and external odors. Because of this, people often are able to wear their merino clothing many times before it needs to be washed.

The Wool Misconception

You already know what wool is, so when people tell you to wear merino wool underwear or t-shirts, you think they are crazy because wool is itchy. And you are right, wool is itchy. But merino wool is not itchy. It’s best to not think of merino as wool, and instead just as merino.

There are some people who do find merino to be itchy, while many will say it’s an allergy, in many cases it’s just sensitive skin. Additionally, not all merino is equal, as the larger diameter fibers, and thus cheaper, merino is much more scratchy feeling on your skin. But in general ultra fine and fine merino wool is as soft as cotton to most people.

The Downsides

Aside from those who are sensitive, there are a few downsides to merino wool.
The first downside is durability. Merino wool is not inherently fragile in clothing, but it also can be prone to pilling (those little balls of fabric you get on sweaters) in areas of abrasion as well as snags. So while it generally holds up as well as soft cotton, there is some risk with it. In some items, the merino is blended with synthetic fibers (such as nylon) to provide some extra strength and durability to the fabric (however, this can interfere with some of the odor resistance).

The next downside is care. The best way to care for merino is to not hang it, and to wash it in a delicate washer (or hand wash), with special soap, and air drying. This can be a deal breaker for some, but also is quickly something you get used to.

The biggest downside of merino is the price. There’s not a lot of merino wool out there, and thus it’s an expensive material to work with. Rarely will you see a merino t-shirt dip below the $60 per item mark. Even though it will last (and you will need far fewer garments), it’s a high barrier to entry.

Our Thoughts

While many people debate about the odor resistance, we’ve found that allowing the merino to air out between wears typically will wipe away any smells in just a few hours.

Merino is well worth the high cost of entry, and will likely cause you to drastically pare down your wardrobe as merino clothing can be worn many times in one week without looking or smelling dirty.

Where we like it

The absolute best starting point for merino is socks. They are simple, less expensive than other garments, and very effective tools for showing just how amazing merino is. Our feet sweat throughout the day, but with merino wool they will stay comfortable. Often you can wear the same pair of socks all week, and never detect a smell from them — even after hard workouts. So if you are new to merino and need to test the water, get a pair of socks.

Beyond that, the only garments made of merino we have yet to find in a piece we love is in pants. Otherwise underwear, dress shirts, t-shirts, sweaters, sweatshirts, and everything else is pretty great in merino.

Woolly Clothing Shirts

Around here, we love merino clothing, and T-shirts are certainly a staple. Woolly Clothing Co. makes 100% merino T-shirts, henleys, etc. Their T-shirts come in two different weights (150 and 190 gsm) and the rest of the products come in one weight only.

What I Tested

I have a Short Sleeve Crew Neck Tee, Short Sleeve Ultralight V-Neck Tee, and a Long Sleeve Henley. I’ve been wearing them for almost a year now and have certainly put them through their paces.

Fabric Difference

The 150 gsm (what Woolly calls ultralight) and 190 gsm fabrics are quite different. The heavier fabric has shown more pilling (or maybe more aptly described as “it has become fuzzy with wear”). The ultralight fabric is certainly lighter, but is not what I would necessarily call ultralight. Both fabrics are soft and not scratchy/itchy.

There is a definite difference in warmth between the two weights. On some warm summer days, the 190 gsm fabric was almost too warm. The 150 gsm fabric is perfect for year round wear and the 190 gsm fabric is great for a henley.


These shirts fit me extremely well. They are fitted, but not too slim, and they are just the right length. I have had no issues with bacon neck and the button placket on the Long Sleeve Henley hasn’t become distorted.


After I washed my Long Sleeve Henley the first time, I found a hole near the side seam. When I contacted customer service, they were very responsive and sent a replacement. I just recently discovered a similar hole in the same location on my Ultralight V-Neck (I’ve had the shirt for about a year). This time customer service suggested it might be moth damage. I have reservations about this as my closet has plenty of other tasty merino that has not shown any signs of moths. Since the hole occurred in the same place along the side seam on both shirts, I can envision a possible issue when the fabric was sewn.


If you don’t care to advertise the brand of clothing you are wearing, Woolly puts a fairly large tag on the bottom hem of their shirts. The tag blends in with the black fabric much better than the charcoal. This is not a dealbreaker for me, but not my favorite thing either.


The Woolly shirts are not my favorite shirts, however, comparing the 100% merino shirt market (at full price), these shirts are certainly a good value. The fit is also great. Many times I run into shirts that are either too slim or boxy, but these are cut perfectly.

My reservations for recommending these shirts are the “fuzziness” that develops and the issues I’ve had with holes.

What are Synthetics?

You will find that most athletic and outdoors clothing is made with synthetic materials for their improved properties over traditional natural fibers such as cotton.

There are may types of synthetic and artificial fibers including rayon, spandex, lyocell, modal, nylon, and polyester. Most of what you will find in the clothing we talk about is nylon and polyester (and some of the more unusual, naturally derived artificial fibers). Nylon and polyester are made from petrochemicals, while the artificial fibers come from cellulose derived from plants. These fibers are formed by extruding liquid polymers into air or water.

A lot of the properties of synthetic fabrics not only come from the fiber itself, but also the weave/knit of the fabric (think fleece vs. a wicking workout shirt, both are made from polyester). In many cases, synthetics can also be blended with natural fibers (like nylon core merino wool).

Nylon vs. Polyester

Nylon is a stronger fiber than polyester, making it a great candidate for bags and blending with other fibers for strength.

Polyester has the upper hand in moisture control. While both fibers are hydrophobic (they repel water), nylon absorbs more water than polyester, resulting in a fabric that can be heavier when wet and take longer to dry.

Artificial Fibers

The naturally derived artificial fibers, such as lyocell and modal, (remember these are plant cellulose, but are still manmade) have many of the same properties as natural cellulose fibers (cotton), but have some advantages such as softness or wrinkle resistance.

The Benefits

There are many benefits synthetic fibers can impart on clothing including durability, stretch, wrinkle resistance, moisture wicking, water resistance, wind resistance, and stain resistance. These properties make the fabric popular for harder use garments (like outdoors clothing and activewear). Over time, these fabrics have started to make it into dress and casual clothing for the same reasons. They can even make your blazer more comfortable, durable, and have the ability to go in the wash.

The Downsides

Synthetic fabrics tend to smell more quickly and retain smells longer than some natural fibers (in fact, it has been shown that some bacteria that produce odors love to live on polyester).

Synthetics also can be more staticky than natural fibers, and they also melt when exposed to heat/flame (or an iron).

Our Thoughts

Synthetics certainly can mimic some of the performance characteristics of our favorite natural fiber, merino, but also can impart some downsides. Mainly, synthetics are used when durability or cost are top considerations.

Where We Like It

We like synthetic fabrics for their stretch and durability, especially in garments like pants, shorts, and outerwear. They can also be great blended with fibers such as merino, with the resulting fabric having unique properties such as stretch or more durability. One great example is NYCO, a nylon/cotton blend. Some others include merino with a nylon core and merino blended with lyocell. These fabrics all retain some of the good properties of their natural fiber component while improving performance with the synthetic fiber.

Bluffworks Gramercy Blazer

Note: this blazer was provided by Bluffworks for the purposes of this review.

If you’ve ever searched “travel blazer” then you are likely to know that most offerings look — well they don’t look particularly great. These blazers tend to focus more on wrinkle resistance and “secure” pockets than they do on style. So the more you look, the more likely you are to give up.

That’s where Bluffworks comes in with the Gramercy Blazer — the goal being to make the best blazer you can get for travel and life. They’ve set the bar quite high for themselves, so let’s see how they did.


Fit of any blazer, off the rack, is always a bit of a gamble and will largely depend on your body as much as it does the overall cut. That said, the Gramercy fits me very well, with plenty of room for a light sweater over my button up, or just the button up.

More than the fit itself, is how well the blazer moves as you wear it — this adds greatly to the comfort of the jacket. I followed the sizing guide very closely when choosing a size and that’s your best bet with this blazer.

The fit is also helped by there both being a standard cut and a slim cut. As someone who typically needs a long jacket, I found the regular had plenty sleeve length.


As I mentioned in the opening, the biggest issue you often run into with a travel blazer is that it looks like a travel blazer. The Gramercy looks nothing like a travel blazer. You might notice up close that it’s not quite a normal looking wool blazer, but you’d really have to look closely.

You give nothing up with this blazer. The Blue Hour color I chose is a fantastic and versatile color. It’s best to compare this with a standard blazer, than it is with other travel blazers — it’s too far ahead of the looks of any other travel blazer.

Travel Features

There are three features of this jacket which make it a travel blazer: washable, no wrinkles, and pockets. I’ll talk about laundering it later, so for now let’s focus on the other two.

The blazer comes folded up (who knows how long it sits like that) and yet there were only light creases in the sleeves. I’ve left it wadded in the corner, I’ve driven on long drives with it on, and otherwise done things with it that I might not normally do with a blazer. For the life of me, I can’t see a wrinkle. I’ve not folded it up and shoved it in a suitcase for travel, but then again I would tend to wear this on the plane, not pack it.

It’s really good at resisting wrinkles.

I get annoyed with people slapping a few dozen pockets on a jacket and calling it a travel jacket. It’s beyond silly. Bluffworks is walking a fine line here.

There’s your standard exterior breast pocket, as well as two hand pockets on the front. There’s nothing non-standard about these pockets, which is refreshing. Inside the jacket there’s a bevy of pockets. There’s two inside breast pockets. The left features a button closure, and a dedicated pen pocket which is nicely confined from the main pocket so your pen doesn’t scratch your phone. On the right there’s a zip close pocket. Which has a zipper pull that never jingles and never gets in your way.

Moving down the inside of the jacket there are two more pockets you’ll need to open with a seam ripper (if you want, I’d recommend you don’t). These are both giant pockets and can hold a lot of stuff. They have no fastener to secure them closed, but they are deep.

The issue with these pockets is when you put anything with weight in them. Doing so tends to quickly telegraph through to the front of the blazer and causes the bottom edge of the blazer to bulge. It’s not a great look. You could drop a small notebook or some business cards in here, but you need to be careful. If looks are your top priority, I’d leave the pockets sewn closed.

Lastly there’s single pocket which vertically zips closed at the back tail of the blazer. It’s an odd pocket, and Bluffworks shows it being used to hide cash. I can see that, as cash wouldn’t be too bulky or uncomfortable when you sit down. Otherwise, the pocket can almost be forgotten about.

What sets this jacket apart for me, is that even though it has these “standard” travel features, they don’t detract from the jacket. If you want to wear this as a normal blazer, you can, and you won’t pay a penalty for choosing one with extra pockets. Well done.


My single biggest concern with this jacket was the material. All Bluffworks says is: “100% technical, breathable quick-dry polyester. Mechanical stretch.” When I read a statement like that I think of something that will make a swishing sound as you wear it, and won’t really stretch.

I was wrong on both accounts.

Let’s look at stretch first. Stretch is incredibly important for comfort, and mechanical stretch means there’s not stretchy fabric like spandex or elastic in the garment. And yet, you might think there is in this blazer, because it stretches a bit. Not enough where you feel like it’s a stretchy jacket, but enough that you appreciate it when it does move with you, which is perhaps a better way to describe it than using the word stretch.

So what about the hand feel? The fabric is soft and smooth. There’s no more sheen than on my wool suit, and it makes no more noise than my wool suit as the material rubs against itself. Simply put: if I didn’t know better, I wouldn’t think this was polyester. It doesn’t look or feel like it.

The jacket feels great. The material is great. It’s breathable while being heavy enough to have solid structure. However, it won’t be warm.

Wash It

A couple weeks ago Bluffworks sent an email telling you how to wash your Gramercy blazer. Now if you’ve owned a blazer before, you know you take it to the dry cleaner. This blazer can be put in the washing machine and will be no worse for wear.

The instructions are simple:

  1. Wash on medium temp
  2. Dry on medium heat for 10min
  3. Hang to finish drying.

Normally I would file this under “good to know”, but given that I didn’t spend my hard earned money on this blazer, I decided to give this a go and see what happens.

I washed the blazer following those steps almost exactly (I dried it for only 8 minutes as I had to leave the house). When I first hung it to dry it looked a little sad — droopy. However, after it fully dried (took about 8+ hours) it looks exactly as it did before I put it in the wash. That’s a bit more magic.

Looking at it very closely I can tell that the lapels have lost a little bit of the press, however that seems to have gone away after wearing the jacket again. You would think machine washing a blazer would be a catastrophe, and it would be, except with this blazer.


One issue I always run into is what to wear when I travel. Often a button down is all I need, but sometimes I get a slight chill — this blazer is going to be my new go to. It looks sharp, performs well, and is comfortable.

I was worried about a lot of things with this blazer, and they were almost all immediately proven wrong when I pulled the blazer out of the box. I really love this blazer. Bluffworks calls it the “ultimate travel blazer” and I concur.

What is NYCO?

A increasingly popular choice for clothing fabrics among outdoor/tactical focused brands like Prometheus Design Werx and Triple Aught Design is a fabric called NYCO — which is a nylon/cotton blend. [Outlier[(https://outlier.nyc/) also uses this fabric in select items. The exact blend varies between companies with some in a 40% nylon, to others closer to an even 50-50 split.

This is quite a interesting fabric for items which straddle the line between performance and traditionally garments.

The Benefit

The key benefit to adding nylon to cotton, is strength. Where cotton can be a relatively weak and wear prone garment, nylon tends not to be. On the flip side, a 100% nylon garment is often not comfortable, and not desirable looking. A NYCO blend gives you the best of both worlds: look and feel of cotton, durability and strength of nylon.

One thing to also note, most garments of this nature are coated with a “DWR” coating, which is a durable water repellant. This simply makes water bead and roll of the garment, but does not waterproof it. It will wear off over time, but while it’s there the largest benefit is that it will help repel stains nicely.

The Downside

The downside here is that you are not gaining many of the typical “performance” elements we come to expect for better engineered clothing. There’s no stretch, or temperature regulation gained. It drys slowly as well, and absorbs orders like any other cotton good.

Our Thoughts

There can be some really good applications of NYCO. Especially for people working, or living, in situations where they tend to have weaker cotton or wool goods wear out quickly for them, NYCO can be a great alternative. Some of the harder wear applications being done are perfect uses for NYCO, and it is especially good to boost something which you want to look traditional.

While we wish there were more performance gains to be hard, it is a very good option for select goods.

Where We Like It

There’s two really nice applications of this: Outlier’s NYCO Oxford, and Triple Aught Design’s Rogue RS jacket. The oxford looks like a typical oxford button down, but with the addition of nylon, it should last for a very long time and be incredibly durable when compared to all cotton alternatives.

The Rogue, is another great application where you get a traditional looking light jacket, with a lot more performance. You can beat on a jacket like this without worry it is going fray and get worn holes in it quickly. Exactly the type of application NYCO excels in.

Where it is harder to make the case for this fabric is in pants. While the brands listed above have experimented with them in pants, you need to look for added stretch to get a better pant out of NYCO. Some brands, including Outlier, do just this, but you are still getting a pant that will not perform as well as some other fabric choices.

Wardrobe Simplification

I’ve managed to pare my wardrobe down quite a bit by using two questions: do I want to keep this; will I actually ever enjoy wearing this? Amazingly, I got rid of the vast majority of clothes I own just by asking myself those two questions. My initial pass through my clothes was simply asking myself: do I own a better version of this / would I like to own a better version of this? If I owned something better, I gave away the other, and if I wanted something better, I put that back on the shelf as a possible reward to myself for getting my clothing under control.

With fewer items, I’ve found that I have settled into a pretty consistent routine with what I wear. But more than that, there’s a lot less stress around my clothing. I am always wearing stuff I like, and stuff I want to wear. Here’s the routine I’ve fallen into.

Standard Work Clothing

I didn’t think I had a set wardrobe I put on for the average day, but then I realized that I most certainly do.

If all I have on the schedule for the day is working (I work at home) my dress is typically:

I’ve found this to be an exceedingly comfortable set of clothes. And without even realizing it, it’s what I pick more often than not. It also works well if I want to dash out of the house to grab some food or get the kids from the bus. Overall, this is the core of what I wear everyday.

Standard Day Clothing (Out of House)

As with the last, this seemed to work itself out without much conscious thought.

  • Outlier Futureworks (sandstorm, which is basically khaki), or Slim Dungarees
  • Outlier Ultrafine Tee or Wool & Prince button down shirt (temperature dependent)
  • Outlier Socks
  • Allbirds Runners
  • I might add layers on this if the weather is cooler, from sweaters or jackets

I wear the Futureworks when it’s warmer than 70° and switch over to Slim Dungarees as the weather cools, but otherwise I’ve been pretty happy with this setup. It’s comfortable, presentable, and did I mention comfortable? With really cool weather, I’ll wear my Strong Dungarees. Though my tops stay the same, I add layers to stay warm.

Standard Evening Clothing (Out of House)

Typically, I want my evening clothing to be a little nicer, because if I am out in the evenings it means I am kid free for a change. So here’s what I’ve standardized on:

  • Outlier Slim Dungarees (either Dark Indigo, or Charcoal)
  • Wool & Prince Button Down or like dress shirt
  • Darn Tough Socks
  • Clarks Desert Boots
  • Blazer/Sportcoat (Currently either the Bluffworks Grammercy or the Taylor Stitch Telegraph)

This should last me well into the cool season, with the addition of a jacket. I like how the Slim Dungarees dress up pretty easily, yet remain comfortable at all times. I’ll likely trade the blazers for warmer layers in colder weather.


Since picking up the OG Climbers from Outlier, they are my go to pant anytime I can wear them. They look extremely casual, but have replaced all my warm-up or sweat pants. I wear them every evening and every morning before I get dressed for the day. In a pinch, they work just fine out of the house, but they look the most technical of all my pants. Typically I pair this with a cotton t-shirt I still have loads of.

Still Looking For

There’s only two things I still feel I need to round out my wardrobe:

  1. Dressier Pants: In the warmer months my Futureworks filled this need fine, but now a khaki pair of pants isn’t great. While I have a suit, I’d like to get something in between and suit pant and my Slim Dungarees. I’m not sure where I will end up on this one.
  2. White dress shirt: There are not many good options. I have looked at everything out there for a replacement for my standard white dress shirt, for wearing with a suit, and I’ve yet to find one I am willing to pull the trigger on.


In addition to all of the above, I’ve switched all my socks to merino and all my underwear out to the ExOfficio Give-n-Go boxers. I only wear cotton t-shirts at night, and I’ve donated half the cotton t-shirts I had. So when doing laundry, the only clothes which ever need to be folded out of the family pile are my boxers and a few t-shirts. Which is rather comical to me. I mean, my clothes never look or smell dirty, and yet I hardly wash them in comparison to all the other clothing in this house.

I was mostly worried about lack of variety in my clothing over a long period of time, but thus far, it has not been an issue at all. In fact, I feel like I don’t rotate through the few clothing options I have enough as it is.

I didn’t list my Ministry of Supply Apollo polo shirts above, because my Lavender shirt came out of the wash a few weeks back with odd discoloration, so I donated it. This leaves me with just a medium gray, which I don’t wear often. I hope to find different options for these next spring, but am waiting until then.

I have cut down on all my duplicates, but kept both the Dark Indigo and Charcoal Slim Dungarees. They are both so very close in color, in that they are both the same level of darkness. I bought the Dark Indigo first as people said it was closest to “denim” however I find that not to be true and still might part with them (my wife likes them, and says I should keep them). I really do like the Charcoal color though, and it’s a winner for me.

I am now in the hard part of this experiment. I truly have almost all I need, and anything I buy now is not because I need it in any way, but rather because I want it. So can I resist? I don’t know, but I want to try. Additionally, I still have a standard pair of jeans, and have yet to bring my self to get rid of them, but truthfully I cannot remember the last time I wore them.

Wool & Prince Button-Downs

Wool & Prince started in 2013 with a 100 day field test of their 100% merino wool button down shirt. Yes, you read that right, the founder of the company wore one of their original shirts for 100 days in a row without washing or ironing. That’s a pretty incredible demonstration of merino wool.

Fast forward to today, and Wool & Prince now makes long and short sleeve button-downs, spread collar dress shirts, work shirts, polo shirts, long and short sleeve tees, boxer briefs, and socks. I have yet to try any of their other products, but they are definitely on my list.

Merino Fabric Weight

130 vs. 210 gsm

The button-downs come in three different fabric weights (130, 170, and 210 gsm). The two lighter weights come in a few different types/prints of fabric (oxford, twill, solid, and tattersall) while the heavier weight fabric comes only in an oxford. The weight of the fabric changes the feel, wearability (comfort, breathability, etc.), and drape of the shirt.

My Experience

I currently own the Light Gray Oxford (130 gsm) and Burgundy Oxford (210 gsm) Button-downs. While neither looks or drapes like a traditional oxford shirt, the heavier Burgundy Oxford comes the closest. The collars on the shirts are nice and stiff and hold their shape (something a lot of merino wool collared shirts struggle with). I can also fold the shirts to pack and take them out when I arrive at my destination with no wrinkling. At the end of the day, there are no wrinkles at the elbows, where the shirt was tucked in, or if the sleeves were rolled up (although it is tougher to keep them rolled than a cotton shirt). The length and the shape of the bottom hem of the shirts also makes them suitable to wear untucked.

Light Grey Oxford

This shirt is very light and breathable and can be almost translucent in the right conditions (so an undershirt is a must). The drape looks most like a standard cotton button-down, due to the very light texture of the fabric. Comfortable in any temperature, this is definitely a staple shirt.

Burgundy Oxford

This shirt is noticeably heavier and warmer. While the comfortable temperature range definitely overlaps with that of the lighter fabric, this is not a shirt for very hot climates (although it will take the chill off in an overly air-conditioned conference room). The drape is closer to that of a standard oxford, however, it feels heavy as it moves (not a bad thing, just different). This shirt is a great staple if you don’t need comfort in very hot weather (as a Northeasterner, this is my favorite shirt in the colder months, although I just wore it in 70 degree F weather and was perfectly comfortable).


Wool & Prince is the leader in merino wool button-downs and seems to be the only one to have gotten the collars and cuffs right. Being 100% merino, I can get many wears out of one shirt, especially when paired with a undershirt. It is possible to get at least a week’s worth of wears out of one shirt (and probably many more). This adds to the value of the shirt; there is no way you can get five equal quality cotton shirts for the price of one Wool & Prince. I’ve replaced all my cotton shirts (with the exception of a suit shirt) with the Wool & Prince button-downs because they are the perfect mix of comfort, style (not too casual or formal), and value.

The shirts now come in “slim” and “regular” fits (check out the extremely detailed size guide). I found the slim fit to be very slim cut and ended up with the regular fit (which is also described as a “traditional” fit). In addition to the cut, the fabric weight makes a difference in the shirt comfort and drape, and that should guide what you pick. I love both shirts and find plenty of occasions to wear both all year round.

Ben’s Thoughts

I’ve had Wool & Prince shirts for over a year now and I absolutely love them. For the price, you can’t beat them. My only complaint would be that the patterns I like tend to be the 130 gsm weight and thus a little thin for winter wear on their own. However if you tend to layer, the lighter weight is excellent. These are the best merino button downs I’ve tried.
