NOT a compression shirt
Color: Black, White, Navy Blue, Wine Red, Size: Large
These are well made with good quality material but are not what I was expecting given the picture. I am an XL and ordered a L because I wanted them to be tight (which they are not.) I decided not to return them because they are good shirts with a reasonable fit, but be advised these are not compression shirts.
