[ This shirt is incredible. I wear them daily during the winter time so I wanted multiple. Smart wool shirts are warm and not itchy at all! I wear them hiking as well as under dressy tops to stay warm in the office.

[ I waited forever to get this on sale and now I wished I 'd bought several in different colors! Warm but breathable, and stylish enough to layer with a jacket for a business casual look. I ca n't wait to take this baby out to the slopes!

[ SmartWool is our go- to for liners. It's well fit, cozy, soft and super warm. It does n't itch and make you warm yet is great to wear inside and on mild days out. Got this one for my wife.

[ Only recently became aware of Smartwool, saw this quarter zip, and love it! Fits well. Looks good. Very useful base wool layer. Now a fan of Smarwool.

5 Rancher
[ Smartwool has mastered the 1/4 zip merino base layer. I 've owned these for years and they never disappoint. Once the temp is below 20 degrees, I have one on every day. Perfect weight, perfect fit.

5 LeoK
[ I recently had the opportunity to try out the Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip, and I must say, it quickly became one of my favorite pieces of outdoor clothing. First and foremost, the quality of the merino wool used in this base layer is exceptional. The fabric is incredibly soft and comfortable against the skin, and it provides excellent insulation and warmth. I was impressed by how well it regulated my body temperature, keeping me warm in colder conditions and preventing overheating during more active pursuits. The natural moisture- wicking properties of merino wool also kept me dry and comfortable throughout my outdoor activities. The 1/4 zip design of this base layer is a great feature. It allows for easy ventilation and temperature control, especially during strenuous activities when you need to quickly release excess heat. The zipper is smooth and durable, and the collar provides added protection and warmth for the neck area. I found the fit of this base layer to be spot on. The slim yet stretchy design contours to the body without feeling restrictive, allowing for a full range of motion. The sleeves are the perfect length, and the shirt stays in place even during active movements. The overall construction feels solid, with flatlock seams that minimize chafing and enhance comfort. One of the standout features of this base layer is its odor resistance. Merino wool naturally has antimicrobial properties, meaning it inhibits the growth of odor- causing bacteria. Even after multiple days of use, the shirt remained fresh and odor- free, making it an excellent choice for multi- day hikes or backpacking trips when laundry facilities may be limited. Durability- wise, the Smartwool Men's Classic Thermal Merino Base Layer is impressive. The merino wool is robust and resistant to pilling, ensuring that the shirt maintains its quality and appearance even after repeated use and washes. I appreciated that it retained its shape and did n't stretch out over time. In terms of improvements, I would have liked to see a small zippered pocket or a media port for storing small essentials or routing headphone cables. This would have added convenience for those who like to listen to music or carry small items while on the move. Overall, the Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip exceeded my expectations in terms of comfort, performance, and durability. It is a versatile and reliable piece of outdoor clothing that provides excellent insulation, temperature regulation, and odor resistance. Whether you 're hiking, skiing, or engaging in any cold- weather activity, this base layer is a worthy investment that will keep you warm, dry, and comfortable throughout your adventures.

[ I ’ ve worn them all. But smartwool has it figured out. They are the best in the business for warmer base layers. I literally wear the crew neck with a 1/4 zip under my uniform. It provides supreme warmth, breathable base, and keeps you dry. And these are flat out durable.

[ Bought for a hiking baselayer. Expensive but I think its worth it. More comfy in the cold than a synthetic baselayer. Not a compression shirt. I use under a fleece. Does n't smell after a full day of hiking.

5 Jackie28
[ This is my second purchase of a Smartwool Men's Classic All- Season Merino LS Base Layer- this is a great lighter weight item that breathes well but is warm enough when it gets cooler.

5 Rover Dog
[ I own several Smartwool tops but this is one of my favorites. The slightly heavier material is ideal for stand alone yet still layers nicely. Never bulky. Quality is what you would expect from Smartwool. Excellent.

5 Tony99
[ I have tried more than one brand of merino tops Keep coming back to smart wool for best quality and fit. They also keep their shape. The price is inline with other brands

5 Thunderbolt417
[ I 've long been an unabashed devotee of all Smartwool products but their base layers, like the classic all- season merino long sleeve shirt, is truly the best money can buy. Since my days of living in the frigid mountains of northern Utah, I 've discovered the breathability of Smartwool's all- season merino long sleeve base layer makes it both the perfect shirt for keeping warm on winter's coldest days as well as ideal workout apparel. Smartwool base layers also make the best all- season pajamas imaginable. The all- season merino long sleeve shirt feels like a gentle hug when you slip it on, and remains comfortable until you 've completed your workout — whether it be a 3- mile hike in the frigid cold or a home gym weight training session. Smartwool has long been the gold standard for merino wool apparel. When you purchase your first Smartwool product, you 'll understand why.

[ 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.

5 sof2024
[ 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!

5 Cutie
[ 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.

5 VermontWinter
[ I bought this as a present for my daughter. It ’s perfect as an under layer for skiing. I can always count on Smartwool for quality products. She loves it!

5 Captain Jimmy
[ This base layer is really comfortable. It is warm and does not restrict movement. I wish I had found this earlier. Fit is true to size. I 'm not sure why anyone would not be happy with this- buy it!

5 Jbear
[ 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.

5 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

5 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.

[ Used to strictly be an Icebreaker tee girl, but found that they just wear out with tiny holes too quickly. I ’ ve been replacing items with Smartwool and have been pleasantly surprised at how they hold up. Way to go Smartwool! Love these tees!

[ Can be dressed up or down. I wear it hiking, to work, and meeting friends at a pub. Do n't have to wash for several wears. It's the high standard quality you expect from Smartwool.

[ 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.

6'. 220lbs. 36H. Average to Long torso. Large upper arms. Ordered: XL I use these for exercise: I do n't have cling issues nor is anything too large. They 've become my favored tops because, for me at least, they just work and fit me well. Fabric composition holds up pretty nice and I 'm not completely soaked by the end of HIIT workouts.

[ Once you start buying wool workout clothing you 'll never go back... It wicks quickly, does n't hold smell, has a great fit, and it comes in my favorite green. 10/10 tank!

Pros: Soft and silky. Fabric is gorgeous and I love the wide shoulders. Cons: The patina green is more of a mint/seafoam in person, and the fabric clings to your body and shows any lumps. Sizing/fit: Very baggy fit. I 'm a size small but I usually size up to a medium for a baggy fit, but I could have sized down to an XS here( 5' 5 '', 120 lbs).

5 K Nicholson
I purchased this top( and the leggings together as a set). Altogether, it is one of the better base layer fits I ’ ve had the chance to try out in the elements. Overall the top is probably my favorite piece, not only because of the high quality materials used- but because of the sleeve length. As a tall/lanky girly, some genuine long sleeves are always greatly appreciated. The style is also a great plus, the outfit goes with pretty well everything( purchased in black for this reason). The outfit looks great together, but they can also be interchanged with other pieces and they still look awesome all while keeping you warm:)

5 Molly

Fit is perfect, it ’s super comfortable- no tugging or readjusting needed throughout the day. Warm without overheating. And it goes so well with my navy ski gear from Halfdays. I always get compliments on the slopes!

5 LaiP
[ I have many wool items but the Smartwool ultralight 120 collection is amazing for hot summers. I wore this hoodie at Disney in Anaheim in mid- August and it offered sun protection while keeping me cool and dry. At night when things cooled off it offered the perfect amount of warmth. I do wish that the collar was a little more open but then it would n't be as great for sun protection. Highly recommend.

5 Transplant
[ Just the right amount of breathable cover and layers beautifully. Perfect for cool evenings and morning walks. Light, light weight and soft to wear.

[ I 've been wearing this layer on the mornings when I hike and it is the perfect weight to keep the cool at bay. it is a little warm for me for sun protection on a hot day but very functional otherwise. I can imagine wearing it lots more this fall and winter. I ordered a Large and it is roomy.. sleeves are just long enough for me. I could have gone with a medium but one never knows these days. am 5'11 '' and 145 and can be either size these days.

[ 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.

5 lightspeed
[ I 've been travelling abroad for several weeks with this shirt and it has been great. It's odor- resistant, dries quickly after a sink- washing, and very cool. Time will tell if it holds up, but so far, so good.

5 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.

5 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.
