This is a very nice jacket. I ordered it for my husband he likes it. He has the black and white one. The jacket fits well, true to size. It is fully lined on the inside with a mesh like material. The tag says 100% polyester. The Sleeve lining is 100% nylon, and the shell is 100% nylon. It repels water and the back has a flap, sort of like an air vent if you will. The jacket zips all the way to the neck and has two zipped pockets. Because it is nylon, it's a bit noisy, you won't be able to sneak up on anyone. In addition, the jacket has a secret stow away pocket with zipper. You have to look hard for it. I only knew about the pocket because there is a sign to embroiders not to sew over the pocket. It's on the left hand side, inside at the top. You'll see a very small pull.
