Giorgio Armani Men's mesh jacket. Size 48

I am selling a like new Giorgio Armani Men's black mesh jacket. I don't know the size of it (my guess is a Small) but here are the measurements. Across the chest is 19 inches. The arm is 27 inches long from the shoulder. And it is 16 inches long from under the armpit. It is black mesh with no lining. The only lining is in the pockets. Two on the outside and two on the inside. The front pockets have zipper closures and there is a zipper closure on the neck that hides a hoodie. (It has not been used). The front of the jacket has a double zipper and they both have strips of leather on them. The bottom of the jacket (on the waist) has Bungies with silver closures. The only tag I found was in the pocket for the size. (see pic). It is lightweight and easy to bunch up and carry. Please let me know if you have any questions about this jacket. Thanks for stopping by.
