In 2014, the OIL voted to award conference champions with a custom jersey based on their team uniforms. The policy was retroactive, so each prior champion of the OIL received their championship jerseys later that same season. The jerseys are produced by HopcoSports.com and are awarded in addition to each conference's respective trophy. And the week 17 Liberty Bowl champion receives a custom mini-helmet. The Dirty Hippies, Dogs of War, ThroatPunchers, and Whackers helmets were made by the OIL commissioner. HelmetNation, LLC manufactured the others and is now the OIL's official supplier of custom mini-helmets.
