The Shadow Classic Helmet is constructed with a high impact ABS hard shell with a light EPS core liner for even distribution of force upon impact. Two sets of our breathable foam pads ensure a custom fit for each rider?s personal needs. Our 10 vent shell was designed to be lightweight and offer the rider great ventilation without compromising the helmet structure and durability. With such attention to detail it?s no surprise that the Classic helmets surpassed all EN and CPSC standards while being vigorously laboratory tested to the highest possible degree.
