Not really a compression garment

This isn't up to the usual standard of Under Armour. This shirt puckers and sits up at the chest. It is the correct size for me, but isn't as fitted as I expected, based on my previous purchase of a compression shirt (with sleeves).

Looks great

A gift for my husband. He looks great in it and it’s a good fit. He really likes it. Thanks

I look buff now.

Exceedingly comfortable. Makes me look buff (I am not buff).

I would recommend this product

I'm very pleased with this product. It's comfortable to wear and I do a lot of yoga and is ideal.

Easy dry

I use to wear cotton under wear and there is no way that in gona wear cotton again . It dry fast and does not stick to the dody . The best product. The shipping is fast and the price is a bit hight but it worth it.


I really liked the compression tank. It feels amazing on the skin and it really looks great on my body.

Superb garment. Used in 37C temperatures. TOP MARKs

I purchased this product as I was playing in the World Masters in Barcelona. Pitch temp was 37C & this under garment was superb. TOP MARKS. It wicked away all my perspiration & kept my feeling superb throughout the 90 minutes & extra time. I have X Armour I use in Scotland but this Heat Gear was even better.

Fits well

Fits perfect and keeps everything in place when running. Due to no sleaves I wouldn’t wear this running with a backpack as it rubs your arms(as I found out). All in all a great product. Keeps me dry when working out and love the colour and style. Good quality products as normal.

As UA Should be comfortable and keeps you cool in hot weather

Best gear out there by a mile Very comfortable and looks good also easily washed and dried.

Excellent Compression Shirt

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.
