Zusammenfassung:A lightweight helmet shell includes an inner shell formed from a porous expanded plastic layer, and an outer shell, in which the outer shell is formed from a compressed fiber sheet having an apparent density of 0.15 to 0.7 g/cc and an impact absorbability of less than 300 G. The lightweight helmet shell has excellent breathability, is lightweight, and has improved impact absorbability.
