Whether you are a mountain biking enthusiast or a fan of rugged trails, the Manifest Spherical Helmet by Giro is the accessory you need to ride with confidence. Featuring spherical technology and the best ventilation in its class, this premium trail-riding helmet is designed to provide optimal protection while ensuring exceptional wearing comfort. The spherical technology used in the design of the Manifest helmet allows the outer liner to rotate around the inner liner during an accident, thus reducing rotational forces and eliminating contact with a hard plastic sliding plane. Airflow is ensured by the AURA reinforcing arch that allows air to circulate through the Wind Tunnel vents. The Roc Loc Trail Air fit system and XT2 antimicrobial padding guarantee a comfortable and secure fit, while the moto-style adjustable visor offers additional protection against the sun and debris. The Manifest is certified to meet CPSC and EU safety standards for bicycle helmets intended for persons aged 5 and older.
