HJC - C91 JYN Modular Helmet - Silver | White | MC1 | Gloss | Red
The C91 JYN is a full-featured modular helmet built for riders who want flip-up convenience without giving up performance. Its Advanced Polycarbonate Composite Shell was engineered with CAD technology for a lightweight, superior fit, and the adjustable chinbar locks down securely when you want full-face coverage. The Advanced Channeling Ventilation System pulls air front-to-back to flush out heat and humidity, and the Pinlock-prepared HJ-17 shield blocks 99% of UV rays while HJC's RapidFire system lets you swap shields tool-less in seconds. An integrated smoke sun visor slides into place quickly and is anti-scratch coated for long-term clarity. Inside, moisture-wicking interior parts keep things dry, and the removable, washable crown and cheek pads are interchangeable across shell sizes for a more precise fit, with glasses grooves that accommodate riders who wear eyewear. A double D-ring chin strap secures things down, and the shell is ready for SMART HJC Bluetooth with built-in speaker pockets, so adding a comm system later is simple. Whether you're modular-riding through your daily commute or heading out on a weekend group ride, the C91 JYN keeps you covered, connected, and comfortable.
