I was looking for a top that I could exercise in as well as shop. This top fit the bill perfectly. The material feels great against my skin& it wears well. After 4 washings, it still looks new. I am so pleased with this purchase that I am ordering another one in a different color.

[ One more high quality product from my favorite brand Nike. This long sleeve thermal top fits me perfectly. It has versatile grey( steel) color. Fabric is durable and dries out really quickly. I can wear this top both with jeans or sport leggings. It is very comfortable and stylish. I don ’ t see any disadvantages. Great product!

Limon1986
[ This trainer is SO soft! I ca n't get over how the inside of it feels like a yummy fleece but without the weight of a fleece jacket. In other words, I live in South Florida where it rarely gets chilly, but this is a great material for a cool morning walk or if you like keeping the AC low indoors! I am typically a size 18 on top and the XXL fits just right, so I would say this runs on the smaller side if you 're looking for a looser fit. The gray color is mild and matches well with various colors. All around, a great top that you can wear to lounge or for an activity.

[ I absolutely love this! The material is very high- quality and feels like velvet on my skin! It is perfect for the fall or winter! I have washed it and it came out great. No piling — it looks as good as new! I love that the zipper isn ’ t a full half- way zipper. It comes down just far enough for me to feel comfortable with it fully unzipped. I really like the small slit in the sides with the back of it being longer. It just adds some extra detail to it. I am 5 ’ 6 ” 157lbs and I have a medium. I possibly could ’ ve gone with a large to have it a tad longer, but overall I think the fit is great! Honestly, there is nothing to complain about it! I love it and get compliments on it!

[ This is a high- quality top! Fitted( but not too tight) and super soft. I 'm normally a medium, and the medium was TTS. Keeps me warm on those cooler morning runs!

Anne
[ I love my Nike Therma fit one top. It ’s sleek and sporty and super comfy. The fabric has tons of stretch for comfort and ease during a workout, but is a good thickness( not as thick as a fleece and not as thin as leggings) and matte and therefore very flattering. I had it on during one of those Fall days where you think “ it ’s probably 65 out ” but it ’s really 50 degrees. And I was plenty warm. I like the length of the top- it sits just below the hip. I am 5 ’ 7 ” and a size 8 in clothes and the medium is perfect with a tank top underneath. I love the soft gray color and subtle swoosh on the side( I usually don ’ t go for big logos!). The collar sits nicely upright with it unzipped. Only thing I noticed that I didn ’ t love is the small neck hole. If you have makeup on and a ponytail( and a big head like I do!) it ’s a snug squeeze and you ’ ll either smudge makeup on the inside of the shirt or you ’ ll mess up your hair if you don ’ t carefully pull it on. Otherwise- it ’s an awesome sleek top.

I received this thermal shirt as part of the carhartt crew field test and let me just say they are amazing. The fabric is soft and silky and they fit true to size. I wore them under my Jean's and tshirt to work and they kept me just the perfect warmth. I wear them about 3 times a week and wash them as well and they seem to be holding up great so thank you for a great product. Definitely recommend to anyone looking for warmth and comfort

I received this thermal shirt to test from carheartt crew and I absolutely love it! It is very comfortable and fits perfectly. I love the moisturizer wicking fabric! It has hidden thumb loops to make it easy to put on your jacket. I would definitely recommend this thermal to family and friends.

AndreaJ
I received the Base Force Midweight Tech Crew Thermals as part of a Carhartt Crew field test and I'am so happy I did because I love these thermals! My favorite part is the thumb loopholes that keeps your thermal shirt in place when you layer over top of it with jackets or sweatshirts. The thermal is very comfortable and kept me dry at all times. It has sweat wicking& prevents odor. You can not go wrong with this thermal and I highly recommend it.

MELANIEW
I couldn ’ t be happier about being chosen to field test this set! As requested I wore these as much as possible( 3- 4 x a week)! These are honestly the best thermals I ’ ve ever worn!! Whom ever designed these thought of everything!! From the warm ultra soft moisture wicking fabric that keeps you dry and toasty, to the stay in place thumb holes in the top for comfort, you couldn ’ t ask for better thermals!!

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!

Jag26
Like the feel of this LS tee. Can use it as a base layer or by itself on cooler days. I personally used it for an outdoor run and felt great. One thing though… while the fabric is intended to wick sweat out, I did notice the tee being soaked so not sure I ’ ll be taking it out for runs again. The length of the tee is also a little short so consider that if interested in this shirt.

[ This color is perfect, very beautiful and should be used again and again. Ideal light weight garment for fitness. Very breathable.

The Greek
[ This is one of two or three of the most amazing clothes I have. Technically it's a base layer but it's something I wear almost anywhere with the right pants and shoes. It's wool, but it's incredibly soft and comfortable. It works great as a base layer, but it's versatile.

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.

It kept me warm for 3 days. All I used was the baselayer and a hoodie with my ski shell over the top. Perfect setup all day long.

I love these for layering or just on their own. The dark red color and the zipper make it cute enough to wear as a sweater, plus it ’s super comfy and warm. I am generally a small/medium( 5 ’ 7 ”, 125 lbs, athletic) and I ordered a small and it fit perfectly. Medium was too wide in my underarms and too long. I live in Florida and use this for winter trips to NY and for winter hiking.
