A single piece, high impact resistant plastic foam helmet having a truncated teardrop shape for aerodynamic efficiency is provided. The helmet design incorporates three ridges centered across the upper front portion of the helmet causing airflow over the helmet to separate from the rear surface of the helmet prior to the onset of turbulence resulting in minimized buffeting of the helmet and reduced drag. A combination of buffeting and a unique retention strap adjustment clip result in greater stability of the helmet on a user's head.
