My husband loves it! I got it for him for Christmas to add to his weird cat tshirts collection. Sort of a silky polyester like sports shirt material. Lightweight but not see-through. He is 6’0” and about 200lb and the large fits great!
Pros
This is a outstanding shirt, nice quality if you like graphics from space this is the one.
Cons
The designs may not be as clear in person as they appear online
