The High Resistant Thermoplastic (HRT) shell boasts 2 EPS to ensure the best fitting, and is now characterized by the presence of a rear spoiler that improves its aerodynamics, making Twist 2.0 incredibly stable even at the most sustained gaits. A formidable Upgrade is hidden inside and is the new ASN ( AIROH Sliding Net) system, which allows an interior sliding in case of impact and extraordinary ventilation for daily use. The adjustable front strap with extension, the sophisticated airflow ducting system, dust filter and Dd Ring retention system create the perfect mix behind its success.
