A premium-quality flip-front helmet, the HJC C91N Kaon Black helmet is packed with features but is budget-friendly. The Advanced Polycarbonate Composite Shell provides a lightweight shell with superior fit and comfort using advanced CAD technology with three shell sizes (XS-S/M-L/XL-2XL). The flip-front chin bar operates with an easy-to-use, single, glove-friendly lever. It also includes an internal sun shield with a manual mechanism that easily moves forward and back and is anti-scratch coated. HJC's ACS Advanced Channeling Ventilation System enables total front-to-back airflow to flush heat and humidity up and out, and the large top vent allows airflow ventilation throughout the deep EPS channels of the helmet, keeping you cool when open. The SuperCool top liner and cheek pad interior give additional cooling features with their moisture-wicking, anti-bacterial fabric, and the cheek pads and crown are removable and washable. (The cheek pads are interchangeable for the perfect custom fit). Glasses grooves accommodate glasses and sunglasses, and the lining also features recesses for speakers for Bluetooth communication. The anti-scratch treated clear Pinlock-ready (DKS008 sold seperately) HJ-17 visor provides 99% UV protection and offers HJC's Rapidfire tool-less replacement system and affixes with a simple and secure visor ratchet system. The C91N is also ready to accept the Smart HJC 10B or 20B Bluetooth systems (sold separately). ECE R22.06 approved.
