O'Neal Defender Helmet

The O'Neal DEFENDER helmet combines low weight, efficient ventilation and refined design, ideal for all-mountain and enduro. Made using double-inmold technology, it integrates a durable outer shell and an inner EPS, with an additional layer that reinforces the edges and improves impact absorption. Large vents and internal channels ensure excellent airflow. The visor is easily adjustable with locking positions, while the Fidlock® magnetic buckle ensures fast, secure fastening with one hand. The fit adapts perfectly thanks to height and width adjustment using a dial.

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

Founded by Jim O’Neal in 1970 in the Los Angeles area, O’Neal brings its motocross roots to MTB with helmets, clothing, gloves and protective gear. Today its US office is in Camarillo, California, and its European office in Vaihingen/Enz, Germany. Its mountain biking journey began in the late 1980s.
