The Bern FL-1 bicycle helmet takes the traditional Massachusetts company DNA and applies it to a fully-vented and super lightweight model. A new premium in-mold construction features a polycarbonate microshell lined with EPS foam to create an ultra-lightweight helmet. The Boa system is a proprietary, lightweight and breathable 360-degree adjustable fit system responsible for near perfect fit amplifying the FL-1s safety measure and incredible comfort. This bicycle helmet appeals to high-end commuters, road riders, and mountain bikers alike.
