My son started coach pitch and was needing a long sleeve shirt to go under his jersey. It was still in the 40s and this kept him warm during the game and practices. It has multiple uses; when playing outside, on a cold rainy day or to layer under jerseys whether they play inside or out.

chandanabells
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.

SkiBear33
4. 0 is the best base layer for the price. My kids are competitive skiers in the Northeast. Our winters are harsh and with windchill the temperatures can drop below zero. Using these 4. 0 as base layers helps to keep their heat from escaping. They hold up well through washing and the boys playing/lounging in them after skiing too. They both have two sets, and I only replace once they are outgrown. I just wish they came in more colors.

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

JG
[ The Merino Tech Lite II Short Sleeve T- Shirt is hands down one of the best t- shirts I 've owned. It's lightweight, soft, and super versatile, making it perfect for everything from hiking to casual wear. Why I Love It: ✔ Soft& Comfortable- No itch, just smooth merino that feels great against the skin. ✔ Breathable& Moisture- Wicking- Stays cool in warm weather and dries quickly. ✔ Odor- Resistant- Worn it multiple times between washes, and it still smells fresh. ✔ Great Fit& Versatility- Works well as a standalone tee or a base layer. A Couple of Considerations: ⚠ Fabric is lightweight, so be mindful of snags. ⚠ A bit pricey, but the quality and durability make it worth it. If you 're looking for a high- quality merino t- shirt that's comfortable, breathable, and perfect for any occasion, this one's a winner. I 'll definitely be buying more!

[ Just reviewed the long sleeve base layer, and like both of these tops. Since it is still winter in Colorado, I have been wearing the short sleeve T- shirt on the 65 degree days we sometimes have. I also like to wear the men's as opposed to the ladies for the looser fit.

Love the fit and breathability, a bit less wool and more synthetic than other brands I wear, but it works for me since this is a hiking base layer that I wear multiple times without washing- does n't get stretched out and dries

[ 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.

[ 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.

[ 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.

[ 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

[ 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.

My daughter is really picky with fabrics that touch her skin. We needed compression shirts to wear under her soccer jersey this winter. She absolutely loves these compression shirts. A little pricey but def worth it. We will be purchasing a few more for her.

Bought these specifically to wear while skiing in the Rockies in Colorado in January. They were soft and comfortable enough to wear around the base of the mountain when not skiing, and they kept me warm when was doing down the slopes. Have no complaints about this shirt. It was perfect

I bought this for my teen to use as a base layer for skiing and sledding. It kept him dry and warm and fit him well. I bought a duofold base later too too and liked the duo fold a little better as far as stitch quality and material quality and the duofold material seemed a little thicker but I ’ m keeping this one too.

Shirts are well made and comfortable. But I preferred the ones from the previous season. Not crazy about elastic thumb bands, they dig into thumb webbing on your hand. They were much more comfortable with the slash cuff thumb hole

[ I am 5 foot and have a lot of trouble finding regular small sizes( other than petite) that fit well in the length. This long sleeve is just right

Love the deep purple, top base layer! It fit really well and was long enough despite my 5' 11 '' height. If you are a C cup or bigger, you might want to size up, but for anything smaller it should work. It's odd that this was long enough but the matching pants are not as I 'm very proportional. In any event, I 'm grateful to have this top and I love the feminine color! Thank you!

[ Bought one in wine and two in black. The wine fit perfectly but the two black ones were tight under the arm, so I returned them. Quality is terrific and it was well appreciated in the cold Montana winds last month.

[ I purchased this shirt, and another in a different color, after having an earlier model. I ’ ve worn the shirts several times now and I ’ m very happy with them. I do think they run true to smallish in size so maybe order up a size.

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!

[ I was looking for wool thermal layer for my husband, who runs cold. Rather than settling on a bland look, I chose this colorblock version for its added style. While he does n't fill it out quite as nicely as the model(!), he looks great in it.
