Will not likely wear before the fall season, but it seems perfect for skiing- light fabric for packing, but plenty of thermal warmth. The color was lovely too- subtle rose!![ for layering... sleeves were not super long, so not need to stuff under your jacket.] Would also come in handy alone for fall golf! Also a great name for teens- I got one for my 16 yo granddaughter as well.

You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.

5
The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!

5
I bought the base layer for my son who works at Disneyland in Anaheim Ca. and he loves it. Keeps hos 3X body warm when working nights. Great product

5 GLWS
Just wearing the shirt and not on has been enough to keep me warm. The few times I have used the heat, I set it on lthe lowest setting and was plenty warm.

5 Luke B
Definitely worth having extra battery banks if you ’ re skiing all day or anything like that, also could use an extra hole in the battery pouch so you can route the cable to a pant pocket more easily. Besides that, it definitely lasts through the wash and multiple winters

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

5 Cupcake
[ 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

5 MehganM
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!

5 Katie
[ 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.

5 Sesb2120

Got this for my daughter, she is a teacher. Her room is cold and then she has bus duty periodically. So the 4. 0 is perfect for being somewhat sedentary. Surprisingly, actually keeps her warm! She is a chilly person normally, so cold temps are miserable for her. We 've tried many products. The Under Armour is work the investment!

[ I bought this Smartwool baselayer top because I really needed something that would wick the sweat away when I was exercising outdoors on those chilly days. This top does exactly what I want.

[ 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

Great for colder or rainy runs to which moisture and keep me warm. I wish it were a little softer but understand that ’s hard to do with wool blends and wool- like materials.

5 KarenB
This top is fantastic in the winter. It ’s light weight enough to be able to layer and the merino wool makes it so warm without adding bulk. I liked it so much I bought the neon pink also. Fits true to size.

5 SgtGlitter
The temperature regulation in this garment is unbelievably awesome. It keeps me warm enough on the start line without getting overheated during the run. It's like magic. I just wish it came in more bright colors.

5 LyndseyK
Soft material, lightweight, keeps you warm and regulates temperature, I love the colour. Runs small so I went up a size. Kept me warm on an 80km ultra

Kept me warm, comfortable, and easy to spot for the 2024 Marine Corps Marathon!

[ 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.

[ I bought the Smartwool to keep me warm and comfortable on a 12 day trek in Nepal. The performance was outstanding and, as advertised, it was very breathable to keep me warm and even cool in the afternoons. It has a very comfortable feel and looks great as well.
