This top is so comfortable. It is a nice space layer and keeps you warm. The color is an added bonus because it is a beautiful light purple. It has a lot of stretch and is great for walking and playing pickle ball. I am 5 ‘ 2 “ tall and weigh 100 pounds and I got them medium children ’s which fits perfect! Arms are just the right length which can be a problem for me in women ’s sizes. I loved it so much that I got two purple ones and one black one!

We purchased this for my daughter to wear under her softball jersey to keep warm during cold spring games. She is a pitcher so she needed something that kept her warm but also was not constricting. This is exactly what we needed. My daughter said it was very comfortable and allowed her the freedom to move while playing softball. She also liked the neck line because she does n't like undershirts that are tight around the neck area.

Really warm underlayer. Used to ski on freezing temp and this plus good ski jacket was enough… even when it was snowing… The only thing is that it feels way different then the 2. 0 shirt. I also have one of that and the 3. 0 is more stiff and feels smaller. Specially in the neck and chest.

I purchased this Base Layer 3 shirt when I visited our local outlet store to place an order for another Under Armour shirt I liked. This shirt is thicker than a normal under layer shirt but is still comfortable if you wanted to wear additional layers. The cut of the shirt is super nice you might not want to hide it, though! It has thumb hole openings which are nice. I wore it alone several times since I bought it and was pleased at how well it kept me warm. I liked it so much I went to get a second one. They had sold out of the 3s but I snagged a 2 at least! My only negative comment would be it looks wrinkled when you remove it from the dryer. I only air dried it so maybe some heat might have gotten the wrinkles out. It's black so not that noticeable. Great shirt. I tried to get a 2nd one so obviously am happy with my purchase!

Awesome standalone shirt for running in the mid- 40s to 50s+ Fahrenheit... or layering when colder. Wicks like a champ, very comfortable and soft.( I 'm always cold... any chillier than mid- 40s and I personally need something heavier.) Also sharp enough to wear around the house or running errands. I love it so much that I bought another.

Ended up buying a 2nd one I liked it so much. Have n't run in it yet as it's still too warm out, but have worn both in casual settings and just taking care of things outside on cool mornings. It's fairly thin so thinking it's suited for runs in 32- 45 F range with a t- shirt underneath and a heavier long sleeve under for temps below freezing. If it's helpful, I 'm 5' 8 '' and 150 lbs with medium build and size Small fits just right.

[ 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.

[ 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.

[ 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.

[ 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.

[ 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!
