Great quality
Size: Medium
Color: White (100)/Black
These were my high school son's go to this baseball season. They wash up great and still look good after a long season. They are great quality and are a great purchase.

Really Comfortable and Beats the Heat!
Size: XX-Large
Color: Black (001)/White
This compression top is really nice. I'm a big guy (5'10" 200lbs- 48" bust and 44" waist) and bought a 2XL per the size chart's recommendation. It fits great; not too tight but definitely provides ample compression. The top is lightweight and breathable, and very good in hotter weather. It's summertime right now and my area gets to around 90 degrees, but I run like a furnace and start to overheat around 65. These heat gear compression pieces have saved me so much grief in the summer. Not a problem or complaint per se, but if I could change one thing though, it'd be how long it is. I know compression tops run a bit longer than an average top so that you can tuck them in and prevent them from rolling up while you work out, but these ones are just a bit too long for my liking. I have to pull them well over my boxers to have them all the way straightened! Luckily, I'm handy with a sewing kit and can alter it to my preferred length. Seriously recommend this top though, will definitely be buying more of them and other articles in the heat gear line.

Greatly improved from previous versions.
Size: Medium
Color: Black (001)/White
Great for warm weather. Fit and fabric are much improved compared to the one I purchased 2 years ago. I normally wear a small shirt but the medium for this is a perfect skin tight fit. Fabric is thinner (but tough) and stretchier. You can feel the breeze go through it and it shows off your abs. Great improvement.
