The DEFENDER helmet by O'Neal combines lightness, efficient ventilation, and refined design, ideal for all-mountain and enduro. Made with double-inmold technology, it features a durable outer shell and an internal EPS, with an additional layer that reinforces the edges and improves impact absorption. The large air vents and internal channels ensure excellent airflow. The visor is easily adjustable with locking points, while the Fidlock® magnetic buckle provides a quick and secure one-handed closure. The fit adapts perfectly thanks to height and width adjustment via a dial.

Matte finish and compliance with EN1078 and CPSC standards complete this professional helmet.
