Engineering & Technical Analysis

The HJC C17 utilizes a proprietary carbon fiber composite construction that significantly reduces overall mass without compromising structural integrity. The shell features a multi-density EPS liner designed to absorb impact energy across varying force vectors, meeting the rigorous standards of both DOT and ECE 22.06 certifications. Internal comfort is enhanced by a moisture-wicking, removable washable liner system that maintains hygiene while providing a custom fit through adjustable cheek pads.
