The Sierra R V.24 by O'neal is a motocross helmet, which is only suitable for off-road driving, on dirt. It is made of thermoplastic, a reinforced hard material of high strength. It fastens with a microlock, which allows you to fasten it easily and quickly. The built-in wireless Bluetooth connection allows you to connect devices with the same technology, such as a mobile phone.
