The shirt and pants were pretty much just loose spandex. Not much 'compression' happening. I was careful to order the appropriate size. The material just isn't very thick or strong. The ad copy shows several different configurations and styles so it can be possible to misunderstand what you 'think' you are getting with reality but in this case, '5 Pieces' is quite clear but I only received 4. Received in the package were: pants, short-sleeve shirt, hoodie jacket and shorts. Looked pretty nice but if you are shopping for genuine compression, I don't think these are going to deliver on your expectations.
