Abstract
A protective helmet having a protective shell, a low friction layer, and a comfort liner is disclosed. The protective shell includes an energy absorbing material and an inner surface. The low friction layer is coupled to the inner surface of the protective shell. The low friction layer may be plastic having a thickness of less than approximately 3 mm. The comfort liner is removably coupled to the low friction layer opposite the protective shell, and includes a low friction material, such as brushed nylon, adjacent the low friction liner. The comfort liner may be removably coupled protective shell with either clips that removably couple to receivers embedded in the brow of the helmet, with elastically deformable couplings that extend from the comfort liner to the protective shell, or both.
