The following lists companies which supply headwear for NFL teams. League rules state that players must wear hats from the team's assigned supplier. But Logo Athletic, Nike/Sports Specialties, Reebok and Starter are allowed 20 exemptions and are able to supply headwear to 20 players on teams where they don't have official designations. Some companies have marketing deals with players on assigned teams; those players do not appear on the exemption list.
