While Purdue Pete may be the athletic mascot, the official university mascot is the Boilermaker Special. Built on a truck chassis, it’s outfitted to look like a Victorian locomotive that Purdue’s engineers researched. For this two-tone dad hat, we went with one of the most recognizable versions of the Boilermaker Special logo used from 1996 to 2012; the logo was in use when the women’s basketball team won its 1999 national championship.
