Liner is breathable, hypoallergenic, and designed for long-ride comfort.The helmet is ready for optional Bluetooth communication system (for example, with the manufacturer’s intercom modules) — useful for touring, group rides, or long-distance travel.

Safety & Certification

Certified under ECE 22.06 and has dual homologation (P/J) — meaning it’s approved for use both as a full-face helmet (chin-bar down) and an open-face helmet (chin-bar up).

Built with multi-density EPS inside the shell for better impact absorption.

Features a micrometric metal buckle chin strap and a reinforced chin strap for secure closure.

Has an Emergency Release System for the cheek pads — a safety feature that allows easier helmet removal by rescuers after an accident.

Reflective safety patches/stickers included (in some variants) to improve visibility.

Ventilation & Comfort Features

The helmet offers adjustable ventilation: it has a chin vent, top vents, and rear exhaust ports to allow air flow through the helmet — helping keep the rider cool and reducing visor fogging.

Internally, it uses channelled EPS to help air circulation inside the helmet, improving comfort on long rides.

An internal sun visor (drop-down) is integrated — useful when riding in bright sunlight without needing external sunglasses.

The visor is optically correct polycarbonate (A-class), scratch-resistant, and UV-resistant.

Visor is Pinlock-ready (anti-fog insert compatible) — many versions include the Pinlock Max Vision anti-fog insert in the box.
