I 'm a tennis player& wear these leggings under a tennis skirt. In winter my outdoor tennis playing requires long leggings& long sleeves. The ColdGear Leggings material has a nice thickness, feels durable, has compression& is soft to the touch inside& out. The waistband is well designed. I like my athletic waistbands around my hip bones; therefore, I adjust all my legging waistbands to personal comfort. I 'm 5' 6 '' _112lbs. I wear UA x- small to be as fitted as possible. I ordered Tall because I like to cover my ankles. This length is about 3/4 '' too long on me, but not a bother since they 're leggings. I like these leggings very much for: Tennis- the compression feels great around my knees& hamstrings. Light Activity- softness, warmth& durability. Lounging- softness& the compression is helpful for circulation.

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.

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.

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.

mrsguzzie
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!

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. It has thumb holes to cover your hands when waiting to bat or on the bases. I would say it ’s the same quality as her old Under Armour mock neck shirt but at a better price.

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.

I purchased this top( and the leggings together as a set). Altogether, it is one of the better base layer fits I ’ ve had the chance to try out in the elements. Overall the top is probably my favorite piece, not only because of the high quality materials used- but because of the sleeve length. As a tall/lanky girly, some genuine long sleeves are always greatly appreciated. The style is also a great plus, the outfit goes with pretty well everything( purchased in black for this reason). The outfit looks great together, but they can also be interchanged with other pieces and they still look awesome all while keeping you warm:)

I do n't like reviews that say `` love these '' or some such, since it tells me very little. So... I am 5' 2 and weigh 152 pounds. My inseam is usually 28 inches, no more than 29. I ordered the large and they were perfect in length, landing right at my ankles with a little sag for give in the knees, and for squatting. I have a bit of a straight waist that is short- the waist band is about a 2 inch band that did NOT roll over or down and did not bind so the waist was just right. Fit perfect in the hips, and I have a butt so they stretched without gapping or sagging down in the back. I washed them in warm water, rinsed in cold and hung them up to dry. Dried quickly. They were warm without being hot, did not bunch in the crotch, and I had on jeans over them. Worked outside on the farm and stayed cozy. Went back and bought two more pairs.

`` Heavyweight '' is a little misleading. The fabric is very thin and see- through. On their own, they do n't feel very warm, but worn under jeans or other pants as intended, they function very well. I forget I 'm even wearing them under jeans, and they keep me very warm on cold mornings. A good comfortable base layer. Got the M and they fit great. I 'm usually a 6- 8 in pant size.

I bought this baselayer to use for my recent snowboarding trip. The weather was windy and 8 degrees each day. I already owned the baselayer pants which were military issued. This top was perfect. 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.

These pants, as well as the matching shirts, are great for when your son's baseball coach thinks it's a good idea to hold practice in January when it's 38 degrees and no tournament until March! You can put this under any jersey or uniform to keep warm. Do n't mess around with the cheap ones you can find at other online retailers. They 're real thin and do n't add much thermal support. You get what you pay for, and these are not a bad price.

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!

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 '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.
