Early Days (1934-1960s):

Information on the exact designs from the team's earliest years (1934-1950s) is scarce.
Historical photos suggest the use of simple leather helmets, likely featuring a basic school logo or lettering.
These early helmets prioritized safety over aesthetics, with a focus on functionality.
The Arrival of the Green Helmet (1960s-1970s):

The 1960s marked a shift towards a more recognizable design.
The iconic green helmet, a color associated with the school since its founding, became the foundation.

Early iterations likely featured a simple white or gold decal with the school initials "NT" or a basic "Mean Green" inscription.
The Eagle Takes Flight (1970s-1990s):

The 1970s saw the introduction of a more elaborate design element – the eagle.
A fierce-looking eagle head decal became the focal point, symbolizing strength and determination.

The lettering and color scheme likely remained consistent, with variations in size and detail of the eagle logo.

Modern Refinements (1990s-Present):

Since the 1990s, the North Texas helmet design has undergone refinements, maintaining the core elements while incorporating modern aesthetics.
The use of metallic or chrome finishes on the green base became prominent, adding a touch of shine and sophistication.
The eagle logo has seen various iterations, with a more stylized and streamlined look in recent years.

Additional elements, like facemask stripes or decals commemorating special occasions, have been introduced for temporary variations.
