Comfortable, but short
I wear this shirt often as a thin base layer when its colder and its comfortable, stays reasonably warm for such a thin fabric, and wicks well. The only issue is its very short. Im smaller and generally Patagonia xs fits me well, but this one is so short that it cant tuck in at all, though the sleeves fit.
I LIVE in This Shirt!
I wear this shirt daily and nightly! I have nine that I wear in rotation. On its own when it's warmer and at night. As a base layer underneath a sweater when it's colder. I am totally addicted! It is supremely comfortable, ultra-light and can be comfortably warn for 3 days, two weeks at night without odor buildup. (I use another for exe... Read Morercise). I have so many because they won't last forever and I don't want to stress them. (I machine wash and hand dry). One request: navy blue! I would buy a half dozen more tomorrow. I have other Patagonia weights for base layer skiing, etc., and another other brand (Icebreaker 750) which comes in blue (more royal than navy) which I really don't wear. Slightly too heavy and too fitted.
Great base layer for sea kayaking!
I wear a dry suit when I sea kayak in water temps south of 65 degrees. I needed a light base layer under my main insulative garment. I had successfully used an old lightweight Patagonia merino LS zip T, but that eventually wore out. I almost went with a 100% Capilene LS shirt, but my experience with Capilene is that it will work, but it also retain... Read Mores an odor, so my selection had to work on a multi-day trip. I came across the shirt which is a merino/capilene bend. Hmmm, may this will work and it did! I now have three of them. It's now my favorite base layer. I would love to see this in a zip-T, but the crew neck does do the job.
Soft Material, Poor Design
The material and colors of this shirt are very nice, however, I felt like the cut of the design was unflattering. If you're working out with this shirt that might not be a consideration, but as a causal shirt not that great (but it could be an amazing casual shirt with a slight athletic cut to the design).

Patagonia Cool Merino is the best
Starting a few years ago, my only running shirts have been light weight wool and of the few brands I've tried, the Cool Merino is the best by far. I have four at this point, but decided to try out the long sleeve as a layer for cooler weather. Given that its summer, I've only worn it a few times, but I couldn't be happier. These are ...

I have enjoyed wearing this shirt, as I walk approximately 6 miles a day. In fact, I wash it after walking and it has held up very well.

Way too short in torso and arms
Awesome fabric, super comfortable and love the concept. I would have 3 or 4 if they fit. Unfortunately its way too short in the torso - barely covers belt loops, no chance of tucking it in - and the arms are also too short, the sleeves ride up above my wrist. So, sadly, its functionally limited to leisurely walks around town. I'm 6'2"... Read More; and wear medium in all things Patagonia. Large would be too big.
Super light and warm
Received the merino wool shirt. Heard so much about the hype and theyre all true. The shirt is fantastic at wicking moisture as I never felt clammy when I was snowboarding. Kept me feeling dry and warm. Its light enough to be worn just under my jacket. I suggested to many others to try this shirt as compares to other base layers. Love it.
Soft and not too hot
Great shirt. Thin and breathes well. Protects me from the sun during the 70 degree winter days we've had in California this season. Perfect for low 70's rounds on the golf course as well as hiking. Good all round long sleeve. Only complaint is the tag down the left side at my waist. Had to cut it off. Way too much tag for such a thin sh... Read Moreirt. Keep making them.

All conditions comfort
You have to love the easy way this sweater wears; for all situations merino wool is the best in terms of flexibility: for everyday casual, a hike, walk the critters, or a fast ride to do errands. From the 40s to the 'Teens it is great for all conditions. Dinner with family, crunching through leaves, or zipping through chilly city traffic it is... Read More the simply the best
Nice but a bit fragile
Sizing is same to the Lightweight Caps, slim yet has space to breath. A bit warmer than Cool Daily, Tho I still wear it on a sunny day but not that it was design for. It would be a great piece for layering while hiking, climbing etc. You can wear it on its on and still be warm (ok warm). The only gripe is the fabric easily pulled, I got few on the ...

We're sorry to hear that this one was a disappointment. This one is a "slim" fit so it may vary greatly from our "regular" or "relaxed" fit items. Please reach out if you'd like assistance to return or exchange. We'll be happy to [help](https://help.patagonia.com/s/)!
Ive head this item for a limited time and cannot yet determine how it will hold up to repeated washings, hard wear and abuse thats why I can only give it 4 stars. Thus far its a good fit, Im 59 and 175lbs with, what I would describe as, an athletic build. The item fits my frame well and can effectively be used as a base layer beneath mid and outer...

Comfortable but delicate
Fantastic experience. Great service! The shirt itself is a little bit thinner and more delicate than I expected. Does not feel like it will hold up after a few washings, but we will see.
Thank you for your feed back on the Patagonia Men's Long-Sleeved Capilene® Cool Merino Shirt. If it does fall apart on you after a few washings, please do not hesitate to reach out to us!
Great as an outer layer
I wear this shirt indoors in winter and a bit outdoors as an outer layer over colored undershirts. I have a similar yellow mango-colored long sleeve shirt that I wear for sun protection in the summer. I am 5'10" and relatively fit (no extra belly weight). Two reasons I bought size Large, which is a loose fit for me:  Medium is the rig... Read Moreht size for me and the size guide is accurate. HOWEVER medium is slightly tight for me when worn as an outer layer over undershirts.  If I wear this shirt as one layer without an undershirt, the thin light-colored fabric shows nipples, which my wife declared is not a good look for me as a man. (Although I think would be a lovely natural look for a woman.)
So Damn Cozy!
This is an incredible top that works from adventure sports to lounging around the house. The fabric is so soft against the skin and extremely lightweight. It is a bit see through as an FYI, if that matters to you but the function of this piece is top notch. I've worn it mountain biking many times and it's shown to be more durable than I i...

Great Shirt, Drying Cord needs revision - breaks after wash
I love these shirts and will keep replacing them as I wear them out. I live in Florida and can wear these on the hottest days and feel cool, and I can wear them in cool airconditioned spaces and feel very comfortable. I wear these in the ocean because they dry very quickly and keep my fair skin from burning up. Buy these, but don't expect the ... Read Morecord used to dry these shirts to hold up.

Material science is top notch! Nips might say otherwise!!
First off I just wanna say I haven't had a bad product from Patagonia (yet). Lets first discuss the pros!! a) color matches University colorways and is perfect for tailgating in the cold! b) fit is loose with this line but fits my athletic bod perfectly! I would say true to size! c) use case: to hiking in cold temps! Even as a baselayer for... Read More skiing/snowboarding! b) thin but versatile I need to test it out on hot days but I see this as a fall/winter piece mostly! CONS: a) if you nip out this may not be the L/S for you! b) piling may be an issue but a special stone can be purchased to relieve this! c) great fit at the top but loose at the waist! - if you have a longer torso this would be great on you! - shorter torso may look wonky unless you have a built upper body!
All Is Well Save the Sleeves
Love this shirt except for the cuffs which I can't pull up much past my wrists. They're just too tight. Maybe with a little wear (and hopefully no tear) I'll have them around my elbows, but not new, not now. I'd love this shirt forever more if you guys just did the sleeves like you did on the sun shirts (with the thumb holes!). ... Read MoreNice and loose, please. Bonus points if you make a version with 3/4er sleeves. In light blue. with feet on it.

I have a 44" chest, 34" waist, 16" biceps (relaxed), broad shoulders (50" circumference), 33" sleeves. The XL fits perfect. Good through shoulders and chest.

Cool in Wool
The long sleeved Capilene cool merino shirt is a perfectly balanced light weight wool layer.

The perfect sunny day shirt?
Ive been wearing my shirt now for a week and I dont want to remove it. Ive layers it under a light tee shirt to contrast the color when I go out on the town.

Read Mores as a base layer for mountain biking as well and think it may be the perfect base layer in any weather. The soft feel of the fabric is unlike anything.

Perfect casual shirt. More colors?
Amazingly comfortable shirt. Dozens of Patagonia purchases for distance running, I use this more for casual wear than as a base layer.

Pretty sheer fabric
Normally I feel that Patagonia sizes run large. I am 61 170 lbs and usually find I am a Patagonia medium. This one seems a tad smallish but what you might expect in a great baselayer shirt. The fabric is quite light and clinging so it is a bit too sheer for me. Although I am fairly well built, at my age I dont think many want to see me in something... Read More so transparent . I have this same criticism of a lot of performance shirt fabrics. My favorite so far has been the Cool Trail shirts which have a cotton weight feel to them. If I like it you can probably bet it will be discontinued. Haha.
This is my first merino light long sleeve from patagonia and its perfect in every way. I have an outdoor voices merino long sleeve and this absolutely trumps it. Thank you patagonia for your attention to detail. Lightweight for fall and spring layer and even in the summer for under 80 temps. Bought two colors just so I could make sure I had enough
The perfect shirt doesn't ex......
I wore this shirt while hiking in the southern Utah desert for 8 miles in 80 degree, sunny weather. This shirt keeper me cool and comfortable. It's super cozy and works well as a warm base layer as well. I'm so glad Patagonia found a way to source wool from a more sustainable method in order to bring merino wool base layers back.
I have a 260 Ice Breaker shirt which is nice in winter but wanted a lighter wool. The Capilene Merino is perfect for spring weather when around the house. Surprising it hold the heat really well while riding my bike,much better then my light weight Castelli wool top which I love too. The Patagonia top is the most versatile of the two.
This shirt is very soft and very solid for the price point. To be 65% merino and 35% polyester, it has the full capabilities of merino wool (wicking, preventing smell, and temperature regulation) and the lightweight feel of polyester. The Sage Khaki color is slightly lighter than on the site, as well as with a little dash of jade. Depending on your... Read More height and arm length, the sleeves offer lots of coverage; for me, they stop right at the radius on my wrist. I have worn this for work, riding bikes, around town, and the shirt still has several uses before it will have to be washed.
Took a gamble and brought this as my shirt for a 7 day bikepacking trip without testing it prior. It did wonderful in a range of conditions (drizzle/windy/sunny and 30-60F) and performed nicely as a base layer when it got a little too cold/windy for it to be worn alone. This shirt is more fitted (than say the cap daily) which is great for being a... Read More base layer. It packs small and is quite light for what it provides. But with that, this is a thin material so if you run cold and/or are in conditions below 25F then youre going to need a heavier base layer. I strongly recommend the cap air in that case. Oh and no smells :) Highly recommended as a technical shirt all the way to an around the house shirt.
Lightweight & Comfortable
Purchased expecting weight similar to past season's Nine Trails long-sleeved t-shirt, but is much thinner and stays comfortable into a higher temperature range. Back to the closer fitting collar, which is personally preferred, but not noticeable as the fabric is exceptionally smooth and comfortable. Size was exactly as expected for a medium.
