I use this as a singlet when at the gym, and an under jersey when playing basketball. The fit and feel means you don't really notice it's there, but it gives you the support you want throughout the exercise. Great product

I own 15 pairs of this sleeveless shirt, and at least one in almost every color. When I dress for work, I wear one of these shirts under, so I am always ready to workout, or to change quickly for a workout. My job requires me to move quite a bit, and the comfort of these compression shirts make work enjoyable. I used to buy the t-shirt form, but then I didn't like how on fitted t-shirts, you could see the under shirt if the lower part of your biceps, and triceps were showing off, wink wink. So, I started buying the sleeveless, and its perfect. These seam lines on this compression are un-noticeable and very comfortable. When I bought my first UA compression shirt over 10 years ago, the seams were more noticeable, but still fine; however, the improvement is amazing. You cannot feel the seam lines, at all! Reading some of the other comments, I am puzzled at the ones who say they were too tight. I am 5'11 and 185lbs, I order a MD, and it fits fine. In the older versions, I used to order a LG because they were more difficult to get one, but I have no problem with a MD in this version. It is a compression shirt, so you do have to put it on, and adjust the fabric to be in the right spot, but not hard at all.

Amazing product for working out. Wear these under my workout shirts, extremely comfortable and get the job done. Have 5 different colors.

No issues with the shirt quality specifically however, I normally wear a medium and ordered a large. the shirt while it is supposed to be a compression, I could barely put it on. I am grateful for the return policy in this instance. IMHO, I could have gone with an XL. Other than that, the shirt appeared to be typical of UA's high quality. BTW I am 5'7" 155, 22% BMI. So..., slender mid-line with strong upper body and shoulders.

These are great. I have several of them and they very comfortable for workouts. [This review was collected as part of a promotion.]

This product runs true to size and fits tightly as described. The hold up well as long as you don't dry in dryer or use fabric softener. [This review was collected as part of a promotion.]

This compression shirt from UA fits and feel like a second skin. Heat Gear technology keeps you cool. I stay in Phoenix Arizona and played a game on a day when it was close to 100F and it was in a open field with very little shade and i could feel this thing working and did not feel the heat for almost a 4 hour long game. The Compression also is really accurate it is not too tight or loose, its just right.... I own one of these and one of the short sleeve one's and couldn't be happier with these. I would recommend these to anyone and they are not expensive also. They are worth every penny... [This review was collected as part of a promotion.]

Great fit and feel. I would like more neck clearance but a great shirt. [This review was collected as part of a promotion.]
