Material: 70% Polyester, 30% Cotton Unopened and brand new, as shown in the photo. It's made of sweat-wicking and quick-drying material, has a name tag loop, and two buttons on the chest. The tag only states the chest size as 57-63. There are no other detailed size measurements. I have not opened and unfolded it, so I cannot answer questions about the length or width. Thank you for your understanding.
