Snowboard helmets are crucial to ensure safety and prevent injuries. Helmets were introduced to skiing and snowboarding some time after World War II, and back then they were made from fiberglass. In 1954, styrofoam liners, otherwise known as EPS (expanded polystyrene bead foam), were used as a better shock absorber, further reducing the damage that could result in concussions. Further developments resulted in helmets not only being more protective but also taking on a more streamlined design to increase the speed of the wearer.
