This helmet features an innovative In-Mold design that takes technology from Bell’s knowledge of bicycle helmets. The design combines the outer shell with the EPS foam, resulting in an overall lighter-weight helmet. The Scout Air medium size weighs in at less than 900 gms. Using five shell and EPS sizes allows the helmet to maintain a compact look and fit. More shell/EPS sizes ensure a better fit to specific head sizes with less need for interior padding to add or reduce volume. The Scout Air is DOT and ECE certified.
