Revi helmets feature a hybrid dual-shell architecture: ABS for durability and polycarbonate (PC) for optimized weight distribution. Inside, a zoned EPS foam is integrated with the ESA (R) Shock Absorption System, engineered and tested to reduce both linear and rotational impacts. Additional features include a precision dial-fit system, Fidlock (R) magnetic buckle, removable liners and ear pads, and audio-compatible pockets.
