Thanks to Dmytro for picking up a shirt that was left behind after one of our games.
It is a large sized, Chinese made (which shirt isn't I know ^^) black shirt with the embroidered orange logo for a company called DiGiCOR. Pictures attached. Please PM me to let me know if you wish to claim, otherwise I will try to bring it down to soccer when I remember to. As to state of cleanliness, unknown and not willing to investigate.
