Ms Capilene® Cool Merino Shirt

True To Size
September 10, 2023

A Must Have!

Great for hiking, biking and running. Also looks great with jeans. I often wear traveling too because it is comfortable and odor resistant on long trips. I have four of these. I wish there were more colors!

One Wash and that was It!

I generally enjoy Patagonia gear, but I had a disappointing experience with this particular shirt. It initially felt comfortable when I wore it, thanks to the merino wool fabric that doesn't require frequent washing. However, when I eventually washed it in cold water using a short cycle and opted for air drying, the shirt shrank and no longer ...

Thanks for the review, Brady. We're sorry to hear that the shirt shrank! You're welcome to return it [in store]( under warranty or you can connect with customer service if you'd like to send it back to our warehouse in Reno, NV; whatever is most convenient for you. We're sorry you had this experience and we hope not to disappoint in the future.

Great shirt

Thin and lightweight, keeps me cool during workouts, and looks great

September 5, 2023

Lightweight Merino Blend Tee

This is an excellent t-shirt for high output activities, even in hot weather. The only nit that I would have relates to the delicate nature of the fabric, which sheds fibers during washing (I use Woolite in cold water). I have had two of these shirts about a month. I will need to monitor how well they last over time.

Love everything but the static

Love everything but the static electricity. Any solutions other than holding on to a grounding rod?

Response from Patagonia
September 8, 2023

Hi Rick, what a bummer about the static cling! A great way to take care of static is by using a water bottle. Just give your shirt a little spritz, back and front, and that should take care of the issue.

Great shirt

Great shirt fits great looks great feels great

September 3, 2023

Great Merino Blend

Elegant merino blend t-shirt. Will be a go to choice for all day outdoor activities. Great choice for all-day gravel rides, for those of us who eschew road cycling jerseys.

August 31, 2023

Love it.

I have been really enjoying this shirt. The material is soft and lightweight. I have really enjoyed it on warm summer days in Wisconsin. I like the merino wool.

August 29, 2023

Very comfortable

Not too warm for a merino shirt. Good fit. Feels great against the skin.

August 29, 2023

Packs small and no stink!

I got my husband one of these to try to take in our camper van and he liked it so well that I got him 4 more! Perfect for having in a limited space and does not get funky between washes like cotton, even after a hard day of hiking. Highly recommend! Note: the lighter colors can be a little see thru.

August 29, 2023

Good for multiple days

I used it as a base layer for enduro/off-road motorcycling. I went through 3-4 complete sweat cycles a day and after letting the shirt air out overnight it wasn't stinky the next morning -- not even the armpits. I wore it for two days and could've gotten a third day out of it but I had packed for two days for each shirt. The shirt has mor... Read Moree structure/feels less flimsy than a 100% merino wool and seems to perform from a oder-resistant perspective about just as well. I'm 5'8", 150 lbs and the Medium fits well.

It's Patagonia!

Love the new capilene cool shirt. Light and fits great. It's Patagonia, 'nuff said.

August 24, 2023

NOT Durable

I want to love these shirts but they are the most fragile merino shirts I have ever owned. After a single use on an overnight backpacking trip, the shirt developed a small hole and started to pill from the friction of the backpack. I've worn this shirt once and it already looks years old. Stark difference from other Patagonia products which ha... Read Moreve held up for years.

Great Versatile Travel Shirt

These are great shirts for travel. Warm, but not too hot; sink-launder easily; dry quickly with few wrinkles.

this is my third one of these shirts. I use them when I travel and often wear them for several days at a time

August 22, 2023

Really want to love it, but really delicate

I wear (wore) this shirt pretty often for casual wear and on hikes. It's comfortable and very lightweight, which is exactly what I was looking for. I even ended up buying a second one! Unfortunately, it's not as durable like many of the other Patagonia products which I own, I discovered shortly after. After a few washes (following the i...

All Good but Piling

The T-Shirt fits well, and is odour resistant. Dries quickly. However after only 1 wear for 4 hours, the fabric has started piling. Seems like its the issue with merino wool.

Hi Zhi Y! Thank you for taking the time to write us a review. We're really sorry to hear your shirt has started to pill. We recommend machine washing on cold on a gentle cycle and laying flat to dry. If the shirt continues to pill and you're dissatisfied you're welcome to [return](

NOT ready for primetime

I'm not sure where we are in iterations of this particular shirt is but as someone who works to have the line perform and keeps their Patagonia gear moving over decades this is a monumental fail. By fail specifically the longevity factor. I've had 4 of these in both long and short and they all develop holes very early on. Little and then ... Read Moreprogressively to the size of quarters. I really wanted to love these and expected to replace all my capilene with this the wool blend. I finally had enough and returned to the local branch of Patagonia where I live. This products felt great was true to size and technically did what is was designed to do, except in one major aspect and that was wear well. If I had gone climbing in J-Tree, it would have been shredded first time out.

August 12, 2023

Looks and feels great

This fabric is remarkably soft and lightweight. The plume gray has some blues in it, not your typical gray (in a good way).

July 25, 2023

Quick drying and doesn't stink

I've wore this shirt a few times now during very hot and muggy days at the Gunks. It dries quick and doesn't smell at the end of the day. Definitely recommend! I am usually between a Small and a Medium, and sized up to a Medium. It fits well.

June 24, 2023

true to size... for once

This XS fits like an XS (rare these days as everything is bigger than labeled--even at Patagonia). Dries quickly and resists odors. I can wear this 2-3 times after runs before washing it. My uses--running and occasionally indoor climbing. I run outside in the elements year round.

June 6, 2023

Very Nice

Bought this for my partner who works in a hot and humid environment and does not like baggie/ relaxed fit shirts. The navy color is nice, material is really soft, merino breathes well, and he likes the fit.

June 2, 2023

The best athletic shirts ever!!

Love these shirts!! So light and loose, perfect for MTB and trail running here in Southern California. They look really nice as a casual shirt as well. I bought xl and also some xxl for a looser fit when riding with the boys.

May 5, 2023

Nice for casual wear, not durable enough for backpacking.

Shirt is great for casual wear - I'm a sweaty guy, and it dries quick and stays super comfortable. However - it is not durable enough for backpacking or what I would consider "real" outdoor use. I got two of these shirts - one I've been wearing around town. The second shirt, I wore for the first time on a short backpacking tri... Read Morep - the shirt lasted two miles. On both sides of the shirt, it got tons of the little "balls" where the waist belt sits (the little lint type balls that you find on sweaters and sweater vests). Worse, on one side, the shirt just fell apart at the seem. This was after only about 2 miles. I've used this same pack setup for many years and almost always wear wool shirts (mostly Smartwool). I've never had these problems even after multiple days in the same conditions. This shirt literally only lasted for about 45 minutes or so. Overall, I'm still giving 4 stars since the shirts are super comfortable, light, and dry well. However, they are just not durable enough for true outdoor use.

Response from Patagonia

Hi Joe! Thank you for writing us a review on the Capilene Cool Merino Shirt. We're incredibly sorry to hear that the shirt started to pill and come apart at the seams so quickly. This isn't the quality we expect out of our gear so we'd consider this a warranty issue. We've reached out to you directly with further assistance.

May 4, 2023

The perfect shirt.

Hands down my new favorite shirt. I bought several for work travels in SE Asia. They are light weight, hold their shape, breathe well in the hot and humid temps, and dry fast. Cannot recommend enough.

April 6, 2023

Odor-Free and comfy

I wear this t-shirt as a base layer when backcountry skiing. It does a great job of wicking away sweat on the climbs leaving you warm and dry for the descents. I'm 6', 180 w wide shoulders and the Large fits perfectly. You can wear this shirt for a 2 or 3 day backcountry tour and it will NOT stink. I do miss the older 100% merino wool t-s... Read Morehirts that were thinner and stretchier but this is a solid alternative.

April 4, 2023

Wool is the best

Nice light weight T used as base layer or solo to run or ride in. Will be buying more!

March 22, 2023

Merino & capilene make a good combo

Great base layer for winter. Transports moisture, keeps me warm. Compared to all capilene, it shrank a little in the laundry -- next time I'll get a size larger.

March 20, 2023

Great fitting shirt for casual or active wear

This line of Patagonia shirts is a staple in my wardrobe. The "slim fit" is perfect, and this plain black shirt is a work staple for me. I would like to have a few more!

February 19, 2023

I've now purchased five of

I've now purchased five of these shirts. I bought my first two in December for a trip to Europe where we (my wife and I) were expecting colder weather than we experience in the Coachella Valley, CA. At Patagonia's suggestion, I bought size L rather than XL and glad I did as my older capilene base layers were too baggy. The best part of th... Read Moreese base layers is that they are so light, yet cozy, you hardly know you are wearing an undergarment (which never happens in the heat we live in). Subsequent to our trip I purchased three more of these baselayers. If I had one wish it is that Patagonia would make a white tee in the same line. If it does, I missed it. I'd buy it in a minute. While I line dry my merino shirts (they dry literally in minutes in our dry climate) you can machine wash them with no worries about shrinkage. Oh, btw, these shirts exude zero smells formerly associated with the old capilene.

Almost perfect

I love these t-shirts and have ordered them 3 times. I love the versatility of the shirt, it is warm or cool depending on the weather. They breath etc. ONLY complaint is they are too delicate.

Good But not too durable.

I love the shirt and I size up for more true to size fit. Usually I wear and XL in shirts but in this I go to an XXL. My only issue is the durability. I have ripped 3 of them. Twice I was pulling it down and my finger shot through. The last one I have no idea how it happened as it was in the shoulder blade. They are really comfortable but for $70 I...

This is the best base layer I have ever worn!

This is the ultimate base layer. It is cool enough for hot summer days and indispensable for layering in winter. It does not smell, even after 10 days on the trail! It does not stretch (a big improvement over its predecessors). It feels so good to the skin, you forget you have it on! It surpasses all other wool short sleeves I have worn over the ye...

Disappointing odor control

When I travel, I wear merino wool shirts whenever possible. Unfortunately, these shirts don't seem to have the same odor-prevention characteristic that I appreciate in other merino wool shirts that I own. I could only wear these shirts for one or two active days before smelling funky, while my other shirts (from other brands) would smell fresh... Read More much longer.

Make this your go to t-shirt for traveling

Wool is the best for almost any adventure. This works well on it's own. Although, I usually use it as an undershirt to make my other shirts last longer between washing. Unlike some other baselayers, these stay fresher longer. And, they're not just for cold weather wear. They work great for all-season adventures.

October 24, 2022

Runs small

Fairly clingy, runs small. It's a cross between a workout shirt, and a casual shirt. Size up unless you're into a very skin tight fit.

October 18, 2022

My new favorite shirts

Really liking these shirts. The material is quite nice, thin, light, cool, and tough. The fit is a bit tight, but not too bad. I am usually not a fan of Patagonia T's, but these are awesome.

October 10, 2022

Only shirt I wear riding

So light and such a nice fit. Keeps odor at bay and seems to have a knack for attracting cool breezes. Love these things.

October 7, 2022

Great T-Shirt

Very nice material. Cool. Resists odors. Nice looking. Feels nice to wear. Versatile. I have two of them.

September 20, 2022

Shrank in the dryer

I love the material and it fit perfect. After my first time wearing it my wife washed the shirt and then put in the dryer. After she pulled it out the dryer I think it shrunk down to the size of a small so I can no longer wear it. I think it is simply a user error.

September 19, 2022

Nice shirt

Fit is good, I'm on the slim side, wool blend works well in most situations. Would purchase again.

September 12, 2022

Best wearing tee I have owned

Too hard to launder - particularly drying flat etc. One is enough. Its not like other wool gear isn't machine launderable in 2022.

September 12, 2022

Lightweight, airy and comfortable

Really enjoying those shirts so far, soft despite being made of wool and quite comfortable. Very thin, which I like, but be mindful if you're looking for something thicker. Great for summer. Appreciate the wool content to keep odors out over the long-term.

September 11, 2022

Cool or warm as needed, but thin

I love a merino tee. My first one lasted some indecent length of time. I like orange, I like merino, it's good. Small caution about the fabric though is that because of how thin it is, you must be cautious. Cuddly kitties can make for an expensive accident.

September 10, 2022

Great Fit & Feel

This piece is just right as a base layer for western NC winters. Really like the slim fit and smooth feel under mid and outer layers. The synthetic blend should hold up better than the 100% Moreno T's of earlier years as well.

September 10, 2022

Great Shirt

Love the shirt! Dries Quick!

September 8, 2022

Great in warm weather

This shirt is great in warmer weather, love the merino content doesn't get clammy when wet and dries quickly. Good fit not to tight. Easy to layer with other pieces. Ive got several 100% merino Ts and they can be a like warm in the summer

September 7, 2022

Bring back the old merino wool shirts

As a somewhat tall and thin guy, I was surprised to find this shirt to fit quite tight. The FABRIC, however, is where Patagonia have now really got it wrong. Although soft, it is very, very thin with poor stretch properties compared to the merino wool t-shirts of ten years ago. (Those contained something like 85% wool / 15% nylon.) The blend of 65%... Read More wool / 35% polyester results in a fabric that is less durable and less comfortable, especially when wet. When damp/wet, the shirt sticks to my skin and is awfully difficult to remove. To take advantage of wool's wicking properties, the fabric needs to be thicker. (Wool and nylon threads elongate when wet, while polyester tends not to.) Beyond that, a thin fabric like this simply becomes saturated. I understand that Patagonia (admirably) strive to incorporate recycled polyester into their textile supply, but I sense that the case of this shirt, that and cost were the only two factors that got considered.

Wow! So impressed with this shirt. Feels good and doesn't itch, wore each of two shirts I brought with me on a trip to CO and they looked great the second day and even better, smelled great!

My go-to shirt

I live in Texas and need a shirt that feels cool. This fits the bill! Great for activities and dries quickly. Only draw-back is that it isn't super durable. A few hole developed after a few wash/dry cycles. Although, that isn't ideal, I love the shirt and will wear it everyday with those holes!

I just did a 1100

I just did a 1100 mile bike tour and this shirt was my mvp (most valuable piece of equipment). I wore it every day for 26 days, washed it out every night, it was dry in the morning. It did not stink and very comfortable. I bought two for my son who is also active. You cant go wrong with this and worth every penny.

August 15, 2022


I love this shirt. Lightweight and cool.

August 11, 2022

Great Fit & Performance

Fits slim - especially after being washed. Super soft & comfortable. Wicks sweat effectively and dries out quickly. I've worn this shirt mountain biking and to work. My only complaint is a bit of nipple chafing but that was only on multi-hour mountain bike rides in very humid climates.

August 9, 2022

True to size-ish

Don't listen to the people who say this isn't true to size. An XS should actually fit even smaller than this, but close enough. GREAT running shirt.

August 3, 2022

Great shirt

I originally got this to be an everyday T-shirt. It turned out to be just a little smaller than I expected, so I started using it as a running shirt. I love it! Best running shirt I've ever owned.

Wool for the win

Got this for ski season but works great as an undergarment for travel too. Helped manage perspiration and odor like a champ.

This is an absolutely perfect shirt. It's super lightweight and breathable so it feels great on hot days, but it's not see through. The cut is great, it hangs loose but is not baggy.

Solid shirt! Kinda delicate.

I have 5 of these shirts, and I really wear them for everything: undershirt, casual T, hiking, running and even climbing. It's not a highly durable piece, though, so I worry how it will hold up long-term, and hesitate to climb in it again. However, in as a general active piece, it's great for hiking or as a trail runner, or similar! It re... Read Moregulates heat even as I'm sweating, and dries out super quicky. Mine gets drenched during a long run but dries out rather quickly when I'm done, and it doesn't hold any odor. I typically wear mine for several days of intense activity without it needing a wash. That all said, it's DELICATE. It can snag and little micro tears appear out of nowhere. It pills a bit but I don't mind that, as it makes it even softer over time. A heavy pack could exacerbate pilling or micro-tearing. Overall, solid piece that I definitely recommend. Hopefully some improvements can be made in it's durability.

July 5, 2022

Great shirt for days running on the trails

This shirt is a nice weight and size for trail running while wearing a hydration vest. It regulates temperature well and doesn't bunch up under the hydration vest.

July 4, 2022

My favorite base layer made even better! You will love these on the river or to out on the town.

The perfect base layer from 10 degrees to 90.

June 30, 2022

Comfortable and moisture-wicking

Merino-blends are great at moisture-control, so this shirt has become a great warm-weather and active wear shirt for me. A great simple shirt for me to wear for nearly anything.

June 27, 2022

Good for all temperatures

My husband wears this for hiking, skiing on a warmish day, walking in the city, and sometimes even for sleep. He loves the feel of the wool, the tendency to stay fresh smelling, and the versatility.

June 9, 2022

light quick dry

Perfect for any activity rowing, cycling and especially for multiday traveling. Easy to pack two, they don't take up much space and can be washed in the sink and worn in and hour or two.

June 7, 2022

Good but light weight

I have tried similar shirts where I didn't like the 2 way stretch. They sag when sweaty to the length of a dress which tugged and was very uncomfortable. The Capilene shirt does not do that fortunately, but shares the other flaw I have found in most running shirts: they are a bit too light weight. If this shirt was a bit thicker, it would feel... Read More more rugged and like it would last longer. That being said, I have experience with merino wool socks and can attest to the material's durability. For now, this is a very comfortable running shirt and I expect mine will last a long time.

Thats why over many years this the company I buy from. Keep the great Philosophy and what you stand for. Thats why you are the very best

Soft and warm

Great soft base layer or just as a comfy tee

May 9, 2022

Tight fit

Lightweight, doesnt hold odors. I would go up a size from my regular.

Slightly long

Slightly long. Just the right height to where it gets caught in my fly zipper when I zip up. My other shirts dont. Overall, the material is the best material for any shirt Ive ever owned. No bad smell on it ever. Super soft. Super comfortable.

All activities, all climates

Just purchased a second one of these I loved the first one so much. Seems to be sweat wicking and smell-proof in all conditions from hot to cold.

Would love a thicker version

I love the patagonia merino + polyester shirts both for sports and casual wear and was sad when they were dropped due to sourcing issues a few years back. The merino combination with polyester has the durability but not the sheen of the merino+nylon that other brands use and I don't like that sheen for casual wear. Unfortunately, I find the ca...

We appreciate your feedback and we're sorry the new style is a bit disappointing. You might take a look at our "slim" fit [Capilene Air Crew]( which is comfortable across a wide range of temperatures and looks as good on the trail as it does in the city!

Great warm weather T

I appreciate this shirt so much I have three of them. These Ts are perfect in warm to hot climates, they hold their shape really well even after lots of adventures and many washes. They seem to not really carry BO which is a relief not just for yourself but others also. Love this T

The best for temps

These shirts have become my daily go to 'uniform" for night shift; with temps ranging from 20 to 50s and then some. The blend of Cap and Mer is utter perfection. Will be expanding my collection and replacing my beloved organic cotton Tees as they begin to succumb to washing, wear and age.

Best active outdoor shirt

I use this instead of a cycle jersey because it is comfy, looks cool and casual, but also because it is surprisingly warm without making you overheat. It is super durable.

Great summer shirt

I use this shirt for casual wear and short distance hiking in the heat of summer (without a pack). It is really comfortable and perfect for those occasions. I think I would want the fabric to be a bit heavier to use under a pack.

Very comfortable and good fit. Great for workouts or even casual wear.

Heavy Pilling After One Hike

I expect more from Patagonia. Especially for a shirt that costs this much and is meant for active use. I bought this shirt to go on hikes. After one hike in calm, sunny weather, it is already showing heavy pilling on the front and back. I am very disappointed in this product.

Response from Patagonia
September 20, 2021

Hi Francisco! Thanks for letting us know about your shirt pilling. When fabrics, especially wool, meet friction pilling will occur. Often this can happen if there's abrasiveness from a pack or something similar. You're more than welcome to return this for a warranty. You might prefer something like our [Men's Capilene® Cool Lightweight Shirt]( which has a fabric that's less prone to catching or pilling.

Beware, I washed as per instructions and after 2 washes I started to see fraying and beginning of holes in near the bottom half of the shirt ! Disappointing

August 20, 2021

Hi Michael, thank you for taking the time to write us a review. We're so sorry to hear that your shirt developed a hole. We definitely expect better durability out of our gear so we're also very disappointed by this. We've reached out to you directly with further assistance!

I Want to Love It

I really, really want to love this shirt. Especially because I purchased two or them! The pros: they are super light weight and soft, definitely the most comfortable shirts I own. I am also so happy Patagonia makes mens XS sizes as most womens merino clothing is super fitted and too long for me, so the fit is great! My only complaint is durability.... Read More My shirts began piling after two wears and only moderate use. I wore a small pack with a 1 belt on a short hike and immediately noticed A LOT of piling on an already thin shirt. This is so important in my opinion as most people purchasing merino wool intending to wear it multiple times while backpacking or hiking and will be experiencing piling as well. I truly want to love these shirts but I feel like my investment isnt going to last very long. I hope Patagonia creates a more durable version of this shirt and hopefully adds more colors as well.

Response from Patagonia
August 11, 2021

Hi Kori, due to the knit of this item, pilling can be more noticeable on a Capilene® Cool Merino Shirt. To prevent pilling, we recommend washing that item either by hand in cool to cold water, or separately in your washing machine on the gentle cycle. It's best to lay it flat to dry rather than place it in the dryer where the fabric can easily get abraded.   To remove pilling that has already occurred, a sweater shaver or sweater stone is an excellent tool and can help the garment look brand new again.  Of course, if you are not pleased with the performance of your Capilene® Cool Merino Shirt, you are absolutely welcome to send those in for a warranty returns evaluation under our Ironclad Guarantee,

Shirt of the Summer

By far my favorite shirt of the summer to be in, whether I am fly guiding or chasing after my toddlers. This shirt has been my go to all summer long here in the RF valley of Colorado.

Great all-around shirt

I have one of the old cotton and capilene shirts that I am literally wearing holes in. I wanted to replace it but Patagonia stopped making suitable a replacement. I didn't really care to much about the price since I knew that I would get at least a decade (if not two like my other shirt) of use out of it. I have only used it once on a longer...

I was sweaty enough that I was getting salt rings on my pack then got a tiny bit of sprinkles on it on the way back to the car. Afterwards, we hung out and chatted over lunch. I was never too warm or cold. The only thing I am worried about is the thinness and getting snagged on a tree or something like that. Otherwise, I am sure I will enjoy this shirt for a while.

This one has limits

This shirt feels so great you'll want to wear it all the time. Unlike many of my other Patagonia Wool shirts, this one has limits. I purchased 3 short sleeves and 3 longs sleeves and the issues are: 1. Shrinks a good amount (washed on cold, dried on low), not a dealbreaker. 2. Can not handle any type of friction from a pack; my day pack straps... Read More caused 2 minor holes in the shoulder/collar area and my backpack belt created many holes around my stomach.

Great fit but not made for all activities

This shirt is so comfy for hiking! But as with other technical shirts from Patagonia this year I have had pilling. It happened on a week of 5-7mile day hikes in the Red River Gorge of Kentucky. Anywhere the waist belt and lumbar pad contacted the shirt it pilled up. This shirt less than other materials.

every day

I bought the predecessor to this t-shirt many years ago.

Thanks for sharing your thoughts on our Capilene Cool Merino Shirt. We're sorry to hear that you experienced chaffing while wearing it, it could be that a different size could make all the difference.

Read Morey small, slender frame. Unfortunately, they typically run out of stock quickly enough that I don't even see them before they're gone. I still have the previous shirt, and there's no comparison in cut and execution. The older shirt I would describe as a tailored T-shirt. The seams are flawless and smooth. The neck is a better fit, and lies perfectly flat, as do the tops of the sleeves. The sleeves are noticeably longer, which I prefer. For many years now, the sleeves on Patagonias short sleeve shirts, in general, remind me of what was available at places like Pennys when I was growing up in the midwest. I thought they were too short and tacky thenstill do. Short sleeves that come up just shy of the cubital crease look and feel much better to me. Shirts that end with the deltoid just don't work for my taste. You emailed me, and asked for a detailed review, and this may be more than you bargained for. But while Im here, lets talk about color. The colors you choose for women's clothing are great, but for some reason you seem to think that men should be stuck in drab, depressing Microsoft blues, reds, greys, black or moss. Or maybe a screaming chartreuse or Microsoft orange for variety. To me, this is mistakenly giving men the short end of the stick. Loosen up! My recollection is that Patagonia didnt suffer from these tendencies in the Kris McDivitt days, and there was a very distinct shift at some point after. But I wasnt paying attention that closely. Because of the general quality Patagonia has tended to offer over the years and appropriate sizes for the small people, I tend to rely on them more than others. But I think there are some ruts that could be departed from, and I imagine youd be surprised at the reception. Could be mistaken, but you asked. Now that I'm finishing up, I see that the page has removed apostrophes and em-dashes from my review. Hopefully, that's not intentional.

April 23, 2021

Quality material, good fit, but still not perfect

This is only my personal preference. But most of the Patagonia t-shirts I have purchased are too loose around the collar. For a perfect fit, I wish they were tighter at the collar. Otherwise, great shirt. Quality material, good length and fit through chest and arms.

Merino is real.

There are so many merino shirts out there. I trust Patagonia to have figured out wear, stretch, and washability. This shirt fits well, wears well, and is easy to take care of. I can wear it comfortably under another shirt or by itself.
