The classic SMU helmet, a red shell with a gray facemask, became an iconic image associated with the program's golden era. This design, simple yet striking, represented a period of dominance and tradition. However, as football equipment technology advanced, so too did the Mustangs' helmets. The introduction of decals allowed for greater customization, and SMU experimented with various designs, including white helmets with red and blue stripes.

In recent years, the Mustangs have embraced a more modern aesthetic while preserving elements of their heritage. The helmet design often incorporates sleek lines, updated logos, and advanced safety features. While the evolution of the SMU helmet reflects the changing landscape of college football, the underlying spirit of the program remains constant.
