A stylish, lightweight urban jet already equipped with Bluetooth, perfect for those who want to ride free... without ever cutting the sound. The HJC F31 Semi Flat Titanium with Smart 11B is the ideal tool for getting around connected, safe and head-free.

The successor to the famous FG-Jet, HJC's F31 now boasts the new ECE 22.06 approval.

A modern jet with high-end technical features, a competitive price tag and a modern, aerodynamic design, the F31 is a wrap-around jet with an advanced fiberglass composite shell, featuring CAD technology for excellent fit, comfort and light weight.

With its advanced polycarbonate shell, designed for urban and suburban use, it offers a good compromise between lightness, protection and price. Its finish brings a sober, elegant style, perfect for all two-wheelers.

The F31 features a long, clear, anti-scratch lens for good face coverage, with Pinlock predisposition (high-performance anti-fog film available as an option), and a smoke-tinted internal sunshield for even greater comfort in bright conditions.

Comfortable, with its moisture-wicking, quick-drying antibacterial fabric interior, fully removable and washable for easy maintenance, it incorporates a high-performance "ACS" channel ventilation system to raise and extract heat and humidity, with 3 upper air intakes and a rear air extractor. The whole system is equipped with an easy-to-adjust micrometric loop, and internal ventilation ducts for extra coolness in summer.

This model comes assembled with the HJC Smart 11B Bluetooth system, fully integrated into the helmet cavities. So you can make calls, listen to music, track your GPS or chat with a passenger, without having to add an accessory that distorts the design.
