The most noticeable changes have occurred in the facemask and decals. Early helmets often lacked facemasks entirely or featured simple bars. Over time, facemasks became more complex to protect players' faces. Decals, too, have evolved. While the core crimson color remains, the placement and design of the Harvard logo and other markings have varied over the years. Despite these alterations, the Harvard Crimson helmet maintains a timeless and traditional aesthetic, reflecting the university’s history and prestige.
