The Original Urban Skate Inspired Lid. Do Urban Riders want to wear a road lid or do you want to wear a skate inspired lid that is built specific for bikers? The Berkeley is designed specifically for Women with a softer and smoother vent design. Bern’s exclusive Zip Mold technology consists of a PVC microshell lined with liquid injected foam that provides a better weight to strength ratio so Bern can provide customers with a lighter, lower profile helmet. Whether commuting to work in traffic or riding for a cause, Bern can’t promise zero helmet hair when you reach your destination, but they can promise to keep you safe and stylin’ on your journey.
