Boys Size 8/Med Long sleeve hybrid shirt

Please view pics die best description. Boys size 8 blue and white Hybrid shirt. Please see the words from pic as I don't believe its wear as my son only wore it less than a hand full of times, but not sure how to explain it 🤔. Blue short sleeve shirt with white sleeve sewn on towards the bottom of the sleeve to have the overlay look making it long sleeve. Very cute shirt with the words DEPT OF ATHLETICS.
