Wilson Protector WTA3211 NPB specification, size SM. I used it with care, but I'm selling it because I no longer have the opportunity to use it. The shoulder straps have been replaced with elastic bands for easier wear. The protective parts are protected with tape to prevent fraying of the shirt and scratches. (I also work as an NPB umpire) How about it? It will be shipped wrapped in air cap (bubble wrap). Please contact me if you have any questions. Thank you for looking.
