Early Purdue helmets likely resembled those worn by other teams of the era, offering minimal protection. As the game grew more physical, so too did the need for enhanced safety. The introduction of plastic helmets marked a significant leap forward, providing increased durability and shock absorption. Purdue's helmets began to incorporate the iconic block "P" logo, a symbol that has become synonymous with the program.

Over the decades, helmet design has continued to advance, with a focus on player safety. Purdue has embraced these innovations, incorporating state-of-the-art technology into their helmets. While the basic design has remained relatively consistent, the Boilermakers have experimented with different color combinations and decals to create unique looks for specific games or seasons.
