This is an Adrian Peterson Minnesota Vikings jersey, AP, for ALL Day. It's an official REEBOK jersey, imported personally from the NFL.COM official shop. I've only tried it on, and have kept it carefully, but I'm selling it due to moving. The size is S as indicated, which is probably around a Japanese L size? With AP's future drawing attention, get it while you can. Price is negotiable. I'm a regular working person, so please understand that it will take some time to ship.
