I DO NOT KNOW FOR 100 % CERTAINTY OF THE PLAYER THAT WORE THIS HELMET. I DO NOT KNOW WHAT GAME IT WAS USED OR IF IT WAS JUST USED IN PRACTICE. I DO KNOW THAT THE HELMET WAS MANUFACTURED IN 2011 AND WAS USED IN THE 2011 NFL SEASON. The helmet is a Xenith, a helmet that was only used in the NFL between 2011 – 2013 seasons. The size is a M(Regular) The helmet shows a little bit of game or practice use. There are a few dings on the helmet. I tried my best to capture the hits during use be it was a bit difficult. Nevertheless this is still a Dallas Cowboys player issued helmet which is more genuine than any store bought “authentic helmet”. The helmet would look nice with a Dak, Zeke, or Bryant autograph on it! I added all decals and put the face masks on myself. However, the padding inside the helmet is original. Due to the only a few players electing to use these helmets it is a bit difficult to find pics of Cowboys players wearing the Xenith helmet. I have found a couple and will include them in the picture section! If you have any questions please let me know.
