Ask motorcycle riders who wear full-face helmets what their main complaint is about the helmet and you’ll always get the same answer: Heat and sweat build up. That’s because most helmets today use fully-fused EPS (expanded polystyrene) or fully-fused EPP (expanded polypropylene)—both non-breathable, insulating materials. New, patented Brock™ Foam, made of partially fused, polymer beads and an elastic adhesive, allows free flow of air in all directions throughout the foam

and around your head, accelerating evaporative cooling and drying. In addition, the elastic component in Brock Foam improves fit and comfort and helps the foam return to its original shape after impact, thereby offering protection for multiple impact applications.
