PREMIER
Some of the indoor leagues I and my sons played in gave out League Champion t-shirts at the end of every season. It was considered to be intimidating to wear them as team jerseys the next season, especially since that implied that the team was still intact.
The days of the event t-shirts and specially those pins seem to be faded but champions t-shirts are still occasionally given. The jackets are something my kids still cherish, surf and a few others only ones still doing that.
