The HJC *C91* is a really good flip-up and touring helmet, and it won't break the bank either. Here's why. The Advanced Polycarbonate Composite Shell, for example. That's one reason why the *C91* is one of the lightest flip-up helmets you'll find anywhere, as well as offering outstanding fit and comfort What's more, the chin bar of the HJC *C91* is easy to operate via a single lever - even when wearing gloves The package is rounded off with a sun visor (with anti-fog coating), a large top vent, and the interior lining with SuperCool shell material. The moisture wicking fabric of the lining helps to keep you cool. The C91 is also *Smart HJC* ready, which means it will take a 10B or 20B Bluetooth system (*available separately). So you see, HJC has a whole lot to offer.
