Although I don't know the significance of the number, I hear it's fun.  The numbers are screen printed in grey (Raiders colors) with a logo patch on the rear.  

This is a high quality 5.3 ounce 100% polyester black mesh jersey with a trimmed v-neck.  Washing machine and dryer safe but for the best results, we recommend cold washing all your items inside out and hang drying.  Made for him, but will always look better on her (unisex).
