Get the strength and light weight of carbon fiber with the impact absorption of plastic, all in one helmet with the WRSI Trident. While most carbon helmets on the market give superior durability, they often absorb less of the impacts strength than plastic. Thanks to it's polyurethane sub-shell, the Trident gives the best of both worlds: a carbon fiber outer shell for strength and a plastic inner shell that absorbs more of the impact. The Trident comes with EVA foam fit pads that line inside for a comfortable and precision fit. The Interconnect Retention System locks the Trident onto your head for an exact fit that won't roll back or forward.
