I bought this when it was on sale for 70% off, not knowing the exact fabric content or if the quality would be as good as other Smartwool items I 've purchased. The construction is pretty good, flat lock seams are well executed and it's comfortable to wear. My biggest complaint is that they do n't list the exact fabric content in the website description. It's 56% merino, 44% polyester. Material is thin, comparable to Merino 150. Fit is slim and a little long. With the light weight of the material the collar has a tendency to fold in on itself if it's slightly unzipped, but I do n't think this can be fixed. Overall I 'm happy with the purchase and would recommend it

[ I bought this about a month ago in black and Heather gray. I do miles of outdoor walking every day and need a base layer for walking in the winter in Vermont. This works well as a first layer a shirt and my down jacket. Washed well in cold water, hang on a hanger to dry.

[ This is my go- to base layer for skiing( or any other outdoor cardio activity... if I ever did one). It's form fitting and has great mobility. I always use merino fabric as my base layer since it's' breathable and odor- resistant. This top kept me warm but not overheated in 30 degree weather with a down ski jacket. I prefer to minimize my layers so this top paired with my jacket is all I need in everything but extremely cold or warm skiing weather. It's also stylish and looks good with ski pants on its own for apres!

[ I love smartwool classic( midweight) baselayers. Live in Ohio where it's freezing winters and these tops work great as a baselayer or a stand alone top. They are wool so they breathe and it dries quickly if it gets damp( Unlike cotton). I have multiple smartwool tops& love them all.

[ Bought two of these to wear under my mtb jerseys and they work fantastic. Dry out quick, keep sweat off me. I 'm 6' 1 '', weigh about 190 and wear a small and it fits just about perfect. I 'd for sure suggest sizing down at least 1 size if you 're using this as an undershirt.

[ This shirt is a game changer, it is soft, has a nice drape, not too clingy and comfortable at any temperature. I have three of these so I do n't have to wait next to the washer like a two year old whose lovey is getting cleaned.

In Avon
[ I am very happy with this Tee. It is lightweight and comfortable to wear and I get compliments on the fit. I worked in the yard for several hours in 80 degree heat and it kept me cool and comfortable. I could have worn it the next day as it did not retain any odor. I was n't certain how the addition of Lyocell to the Wool would affect the breathability of the fabric. I am happy to say it worked just fine! I have not yet washed it but am sure it will live up to the Smartwool standards. Nice to have a v- neck option as not all of us look good in crew neck styles. From a modesty standpoint you do have to be a bit careful when leaning over. I normally wear a medium however based on the review I ordered a small and it fits perfect.

Jassie
[ Overall this shirt is great- flattering fit, awesome teal color, soft and wicking fabric. The only reason I did n't keep it was the v- neck was just a little too low. The shirt's main use would be hiking and I need more sun coverage on my chest. Too bad, because it would be a solid ten if it was n't so cleavy.

Steve
[ I was somewhat uncertain about this since it seemed a bit thin but decided to give it a try since the weather is now dropping below freezing. I love this and wear it almost daily. I generally wear it like a light jacket rather than a baselayer and it is just enough to take the chill off. I also tried it as a baselayer while hiking. It was fantastic. I shed layers while going up to just this and was fine at about 40 degrees. I added a vest when coming back down and not working as hard. Even though I wear it like a jacket, its not going to block any wind so use it under something else if its windy. Overall, I really like this and would 100% buy it again.

[ Merino is THE stuff for active comfort in the cold. The key is staying dry between rain, snow, and sweat... it's challenging. 100%( 95 and 88 also good) merino helps to achieve this goal. It's warm when you need it to be and water( all types) evaporates quickly to keep you from getting chilled from damp clothing. It's got to be part of a system though, and you have to use that system properly or you will get damp and cold. We just came back from five nights in our tent@ an avg. of 26F at night. After hiking all day in these and then, putting on fresh Smartwool tops and bottoms we were warm all night( we could have stayed in the same set if we had to). Medium weight is probably fine for most applications, but do be sure you 've got the right system for the conditions. In summer and spring it's less critical, but in winter( THE best time IMO)... having the wrong gear can make for a miserable experience... and a dangerous one. Smartwool has the added benefit of being able to go in the dryer at home... not all merino products can. That's my take.

JKNOR
[ When it comes to staying warm during the winter, base layers are KEY! My old Smartwool long- sleeve lasted me years of use. Loved my first one so much that when it came to finally replace it, it was a no brainer. Kept me comfortable and warm during winter months of New Zealand, Japan, all the way to the summit of Mauna Kea. I 've never had a base layer fit so good right off the shelf. Felt like it I was putting on my favorite tshit. Could n't recommend it more
