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!

5
Blanetrain
[ I purchased this shirt in a medium being a 6 foot tall 175 pound male and the fit is what most people would call sport like. I like that it ’s a little long because most medium shirts are hardcore belly shirts when I pick my arms up a little.( I ’ m not that type of guy) If you are than this shirt might not be for you. I have a snap button shirt this will go under on my backpacking endeavors this summer. It seems like weight enough to be worn under something without being too hot but I guess we will see. Being light weight makes me skeptical about its ability to resist wear and tear, however I can ’ t speak from trekking experience.

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.

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!

I have the Abisko wool shirt in the long and short sleeve models. When I had a bad fall in Argentina and broke my arm, I had on the long sleeve version. The arm was badly damaged, but the shirt still looks great. I look forward to wearing it when I get my arm out of the cast. Now I can wear only the ones with short sleeves and REALLY wish they came in other colors.

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!

[ No merino wool company compares to that of icebreaker. It feels fantastic while still maintaining all the qualities of merino. I have no complaints about this shirt.

[ 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.

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!

These are the best long underwear going. I mind the cold but not when wearing these.

The fit is loose but not so lose that I would exchange for a smaller size. The shirt is warm but not too warm when inside. Outside it keeps me toasty at 30 degrees and I ’ m always complaining of being cold. All in all, I ’ m very happy with this purchase.

[ 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. Felt like it I was putting on my favorite tshit. Could n't recommend it more

[ Have worn a few times and overall very good. Does n't wick moisture as well as I had hoped but overall keeps me smelling fine after a few days, is comfortable in cold and heat, and looks good( bought black so doesnt show moisture) Downsides are price( all merino shirts are expensive so not that big of a downside) and extra effort to clean( again all wool products).

[ Used this shirt on a 2 day hike in the Whites. Worked perfectly. Kept the moisture off of me yet kept me semi warm. The problem I have with synthetics is the smell. I rock and roll out there and it comes at a cost. This bad boy, you could hardly tell. Passed the wife smell test 😁😁😁
