This is a racing helmet from the 1998 NASCAR season worn by Dale Earnhardt Sr. It is an open-face Simpson model equipped with a microphone, which represented a step forward in safety.
Prior to 1957, the best protective helmets were made of fiberglass and were lined with resilient rubber foam. It was discovered that resilient or bouncy lining materials actually transmitted the force of contact with a hard object to the wearer's skull. The solution was to use non-resilient materials that absorbed the forces of a crash and did not rebound. Earnhardt's helmet was state of the art in helmet construction in 1998. Its lining crushed and did not rebound. After even the slightest blow, the helmet would be replaced with a new one.

Earnhardt's death at Daytona in a crash on February 18, 2001, was traumatic for his fans and for NASCAR and led to improvements in racing safety.
