Product description Airoh Twist 2.0  It seemed impossible, but we were able to improve a best seller. Now the Twist 2.0 is more performing and more aggressive while remaining incredibly light. The HRT (High Resistant Thermoplastic) shell boasts as many as 2 EPS to ensure the best fitting, and now features a rear spoiler that improves the aerodynamics, making the Twist 2.0 amazingly stable even at high speeds. It also conceals a formidable internal upgrade: the new ASN system (Airoh Sliding Net), which allows the inner-lining to slide in the event of an impact and to guarantee an extraordinary ventilation for its everyday use. The adjustable peak with an extension, the sophisticated airflow ventilation system, the dust filter and the DD-Rings retention system create the perfect mix for its success.ECE 22.05 IMPORTANT NOTE This helmet has been built, tested and approved according to the European regulations ECE/ONU R22.05.
