It's black, obviously, with a blue Batman symbol (my favorite superhero) with a white Y over the front (it looks awesome). A couple years later I added a white 3 on the back to celebrate Kyle Van Noy Day, every day something good happens is KVN Day at my house.
I live in Virginia and won't be at the party in Henderson but on the 5th my wife and I are going to be wearing all BYU gear for Austen. I only wish I had room on the back to put Russell in for him. Prayers are with you and your family.
