Easy and quick purchase. The coolest thing was that I was in a hurry and 15 minutes away from the store. I got there five minutes before they closed. They kept the doors open for me and had my shirt packed and waiting for me. I really appreciate their patience.

My daughter prefers to wear these shirts under her jersey, she plays pretty aggressively, jump balls, dives for lose ball etc. this helps prevent floor burn and getting scratched from other players.

chandanabells
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.

I am going to be using this shirt for biking. The fit is nice, it is tight on the body which is good for me because I do not want flopping clothing while biking. Color is also rich. I would also want to wear it for non biking purposes. Overall, satisfied.

I 've been wearing the Under Armour compression shirt for a few weeks now, and overall, I 'm impressed. The material is super smooth and breathable, which makes it great for both intense workouts and layering under other clothes. The compression itself is snug. If you 're not used to tight- fitting gear, it might take a bit to get comfortable.

Tree 78
I purchased the white in XXL. I normally wear and XL and sized up because it's compression. The XXL fit snugly with plenty of compression. As far as cooling it really seems to work. I wore it on a 60 degree day under another shirt and I was actually too chilly all day! I 'm looking forward to wearing this on a hot day. I do wish the sleeves were a little longer for sun protection. I 'm 5' 9 '' and the body length was fine.

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.

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!

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 didn ’ t buy these for softball, to wear as a base layer under my running shorts. There is no padding in these shorts, which makes them perfect as a base layer and not so perfect as a slider short. For the purpose that I bought these for, they are perfect. Length is great and they fit true to size. They are a little thicker material than most thin base layers are, but they are super breathable.
