Johnnie-O sells clothes with a surfer logo. They also sell shirts with University logos. For the “Sully” model, every school is $129 but the Ohio State version is $135. For the Flex Prep model, every school is $99, yet the Ohio State version is $110. Others have same color, same multi color embroidered logo, so no reason to charge more but to let the world know they don’t like Ohio State.  

Johnnie-O was started by the brother of actor Chris O’Donnell—John O’Donnell. They are from the north shore suburbs of Chicago.
