Runs a little small for a change? Sometimes these Winterized/Repel long- sleeve running tops run a size too big, like they ’ re weren ’ t sure if they intended them to be worn as a first or second layer. I ’ m between Men ’s S/M. Small in the DFADV Stride tops because they ’ re huge. This one fits like a first layer, but has juuuuuust enough space if you wanted to wear a single layer under it. Only gripe is that the collar sits a little wonky, unless you have it zipped all the way up.

5 Aprecise
Love these running thermals. Comfortable and stylish. Keeps me super warm on my morning runs

5 Scott84991532
Grew up in NY. Base thermals was what I grew up with all through the 80/90s. I put this on for the first time and bought 3 different colors. It ’s thinner, warmer and much more comfortable on the skin than your traditional thermal. Huge fan! Looking forward to seeing where this style goes.

5 Rizzo
[ When I pulled these tights out the mail I thought ‘ now when the heck am I going to wear these tights in hot behind JUNE? ’ Thankfully laundry day forced me to put these on in 65 degree weather and these were surprisingly perfect temperature. I can ’ t quite explain it, but despite being hot out, these leggings made my legs feel…cool. In addition to the temperature regulation, Nike comes through again with fit and feel. These are smooth as butter and stretchy yet thick. Can ’ t wait to try these out in cold weather.

5 Drea
[ I ’ m 5 ’ 8 180 lbs and this is my very first pair of Nike One TF HR. I love the black sleek look and the way it hugs my body in the right way. They aren ’ t baggy, loose or uncomfortable which is major to me. I have had a lot of workout like pants that would come down, be very loose in the front area and just wouldn ’ t be comfortable. They do seem to stretch quite a bit. When it comes to washing I let them hang dry to avoid shrinkage and lent. I have worn them jogging, doing yoga, and on play dates with my children and haven ’ t had any issues. These Nike pants can be worn in many different ways which is why I love them the most. I would recommend to anybody that has had issues finding reliable workout/ casual clothing.

5 Chuli
[ These tights are top notch. The feel of the fabric on the inside and outside is so soft. I am shorter so the length is perfect for me. They are surprisingly thick and I know in the winter the insulation is going to be perfect. These tights are very stretchy and durable during a workout. And it is a plus that they are not see through when bending over!

5 AC
[ These leggings have a really top notch features; the fit is not tight or loose, the waist pocket has the potential to be useful, and the simple design is easy for anyone to enjoy casually or in a more interesting outfit. The length fit for my frame was more of a full length than a 7/8th, but that isn ’ t really a bad thing in my opinion. The only thing I felt was useful to mention is the high waisted part feels a lil snug, but other than that there ’s no going wrong!

5 Tam
[ These tights are everything! The only thing I didn ’ t like was that they don ’ t have pockets. I ’ m a pocket girl so that was the only thing I was missing. They feel amazing! They are super soft, comfy and feels just right! Definitely need these in different colors.

The only thing I don ’ t like about this shirt is that it flares a little bit at the hips on me. When I first put it on I was being overly critical in the mirror, it wasn ’ t until I realized how cozy this was that I decided no one besides me would notice and even if they did, I ’ m soft and warm. I wore it outside in 34F weather and wasn ’ t immediately cold. I hope there ’s more colors I like because it ’s fantastic.

5 Mamie90
I received the thermal heavyweight shirt as part of a Carhartt Crew Field Test, but I can honestly say that this shirt is necessary for everyone living in a cold climate. I find that the sizing is true, and the small works well for me. The shirt handles being laundered very well, without shrinking or pilling. It has retained it's shape. I wash in cool water, and I use fabric softener in addition to laundry soap. The Carhartt heavyweight poly wool shirt is extremely effective in keeping me warm, and blocking the harsh Iowa wind. I tend to stay cold, so this is saying a lot. I love the shirt, because it is fitted. It works well under clothing, without bunching up. I appreciate the `` thumb holes '' on the sleeves, since this prevented the sleeves from riding up while I put on my sweatshirt. Great quality, superior warmth, and comfort.

5 JulieB
I received as part of the Carhartt Crew Field Test. It is the perfect weight, feels very comfortable and keeps you warm. It has a bit of a stretch to it so it easy to move around in. Very good quality. You wo n't be disappointed.

I received this item as part of the Carhartt Crew Field Test. The fabric is softer than I was expecting and the fit is pretty true to size. They are very warm as an under layer!

[ Super Comfortable and very warm, these bottoms are a great base layer when it is cold. They keep you warm outside or inside and are very soft wool. They can handle the washing machine and fit well under my jeans or Carhartt twill pants.

5 AshleighP
function> material although I am very particular with the texture of my clothing the purpose outweighs the texture. It most certainly works for a very warm base layer.

[ 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!

5 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.

5 NN07
[ 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!

5 swsNH
[ 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!

5 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.

My daughter used this a few times this fall during some cold weather softball tournaments. She said it kept her warm. Wasn ’ t restricting during pitching or batting.

These are amazing! We love them. ❤️ My dad got my husband and I both a set for Christmas like 10 years ago or more. They are still in perfect condition. We use them for hunting, playing in the snow or anytime we have to be outside for long periods of time in the cold. When I go hunting and it's super cold or wind chill of- 15. I wear mine, my husband's and my under armour sweat pants under my hunting bibs. No need for a heater at all. My son told me he needed some bigger under layers so I automatically ordered him this set. He is going to be so excited when he gets the Christmas morning. If you have multiple children you definitely need to get these. They are such a good quality and will last for years if they are taken care of. The adults sizes are pretty unisex in the bottoms. The woman's top seems to be a little more fitted for the breast.

I purchased one of these and liked it so much I went back and got another one. The fit is perfect. But I did have to size up to an extra large which I have to do with all Carhartt space layers for their shirts. But I like the fit and I like the materials. I wear them at work and it's a lot better to sweat in these than it is a cotton shirt. I believe these are the newer models also as they do n't have the sewn on Carhartt tag. Nonetheless they are still quality shirts but are a little on the pricey side at$ 50 each. But still worth it in my opinion.

Little expensive for a base layer but it does its job keeping you warm. I used it a few times and it does work. I will say get one size up runs small. I am 6ft and 185 and my normal is L but had to get an XL.

I had previously purchased a pair of these a few years back. The older version had material that did not stretch as well or a waistband that would stay up. I really like the tight- almost compression like- fit of this new version. The waistband is much better, and the pants actually stay put. So far, I have been wearing these under a pair of shell pants while I ski in temperatures ranging from 10 to 32 degrees. Certainly happy with my purchase.

5 Wild Child
[ I rage- bought another one of these after a medical tech ruined the neckline of the first one during a procedure. Every time I want to put on something warm and reliably comfy, I reach for this top. I intend to buy one per year until I 've replaced every other base layer top I own. Very good quality, good feel to the fabric. I 'm fairly tall( 5'10 '') and the sleeves are long enough, and the body is long enough. So that's another thing.

5 Upshpr
[ For reference, I purchased a Medium. I ’ m 5 ’ 4 ”, 128 pounds, pear shaped, so, smaller on top, curvier on bottom. I got the black which is opaque. I wear this baselayer weight for cross country skiing when it ’s above 30 degrees or so. Smartwool varies in size for me, these are not extremely fitted like some of the 1/4 zips so go with your normal size.

5 KC123
[ I love this shirt. I recently got another few to fill up my wardrobe after a move from AZ to OR. I have had the originals for almost 9 years and wear them all winter long. I have been hiking, backpacking, and traveling with them and they have withstood the test of time. They are comfortable alone or as under layer. I additionally regularly wear it as a mid layer with a smartwool tank below. I truly love these shirts. If it helps, I wear an XS and am 5 ’ 2 ’ ’ and 120- 130lbs depending on the year.

[ 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.

He likes that he can go directly from a zoom call( looks dressy enough on screen) to working outside( durable) to skiing( warmth under a ski jacket). He finds that he wears it most often as a mid- layer, but has worn it next to skin, as well. I am online buying him a few more in other colors right now!

[ Love the quality and softness of these wool undergarments! I got medium top and bottom and they are true to size. I hike alot in the winter in the Smoky Mountains. These garments kept me cozy and warm! Love the mint green color also!!!

[ These are great and probably my favorite pair of base layer bottoms. They are cozy, not too tight and breathe nicely. I ’ d like to buy another pair but my size is out of stock.

[ I am an avid walker and must have my daily jaunt or I will go bonkers. I have hiked in all weather from the cold sub temps of Minnesota to the rainy and windy winters of Texas. Having warm thermals are essential. Searching online reviews, Smartwool keeps popping up. My wife and I bought two sets each of tops and bottoms and she just simply loved them instantly When ever the temp dips she gleefully pulls on her Smartwool NTS and a shell and she is out the doors. The material is just the right thickness and the seams are well hidden. It instant warms the body and as claimed, do not smell after a few uses As for durability we have to wait and see. We have other woolen garments and we can see these products appear to be durable. No regrets buying them but regrettably the color choices are limited due to stocks available.

[ I could go on and on about this whole line from Smartwool. It's their best thing in a very long time and I 've been a fan for years. The material is very soft, has a great but comfortable fit. These bottoms also have a nice wide and sturdy waste band so there is no bunching or other uncomfortable nonsense in that area. These are very warm, so perfect under a shell pant or bib for alpine skiing, but I do n't think I would wear them on a tour.

[ I received these as a Christmas gift. I love them under my bibs for snowboarding! They ’ re tight but flexible and comfortable. They keep me warm on the mountain.

Fit is great. Very warm for Chicago winter runs, but a little bit itchy. Also I would like it to be thinner like the ones in the smartwool Tercel material. Sadly could not find those in mid rise online.

This product does the job of keeping you warm within and I believes will help eliminate injuries

5 JumperRunner
These fit like regular running tights but the lining adds almost no bulk while keeping me warm. Leg zippers make putting them on and taking them off much easier.

5 CMDav
These lightweight tights are much warmer than I thought they would be. I like the leg zippers, and they also have an inside modesty panel. I wear them commando, and they feel great. I do wish they had at least one side pocket and a waistband cord.

This is my first time using running tights, and I have a positive first impression overall. They offer a snug, supportive fit that feels great during runs, and they don ’ t bunch or slide around. The fabric is lightweight but provides enough warmth on cooler days, and it wicks sweat effectively, keeping me comfortable throughout my run. I was initially unsure about switching from shorts, but these tights feel natural and unrestrictive. Overall, I ’ d say they ’ re definitely worth trying if you haven ’ t already.

Very nice pants for working out in. Seem to be high quality as is usual for Under Amour clothing. Only wish they were available in 30 '' inseam.

Used these under sweats in below freezing temperatures in Quebec City sometimes needed snow pants too, other times just the two layers.

5 DreambornAnthology
Love Smartwool for days in the snow. It ’s a great base layer that I can depend on. It is super soft when you first buy it but does get scratchier with wash and wear, even with gentle cycles, mild detergent, and hang drying. I tend to wear a thin, cotton free layer underneath for better comfort and more layers. While it does offer some stretch, it is very true to size, so if you are teetering between sizes, size up. You ’ ll be more comfortable and won ’ t risk circulation compression, which will ultimately make you more cold.

5 Kpave
[ These fit so great! I ’ m plus sized and sometimes sizing can be wonky or vague but these are a dream. They are warm for sure but I can ’ t wait until The temperature dips to really put tgem to the test.
