O'Neal Adventure Helmet

The O’Neal Sierra RS Echo Adventure Helmet delivers high-performance protection for both on-road and off-road riders. Designed for adventure, it combines safety, comfort, and advanced features, making it ideal for riders who demand versatility in all conditions. In addition, its sporty fit, modern design, and Bluetooth readiness support confident, connected riding.

To start, O’Neal builds the helmet with two outer shells and three EPS layers, providing strong protection and a precise fit. At the same time, the lightweight ABS shell ensures durability without added weight, while the close-fitting design reduces movement at high speeds, giving riders better control.

Furthermore, the helmet includes a microlock chin strap for secure and easy fastening. Riders also benefit from the integrated sun visor and clear main visor, which provide excellent vision in all weather. Moreover, the included Pinlock® MaxVision insert prevents fog (not pre-installed). In addition, the helmet is Bluetooth-ready with speaker cavities and a rear cable loop, and it also supports Quin Smart Sensor installation (sensor not included).

For added comfort and convenience, the E.Q.R.S. Emergency Quick Release System allows fast cheek pad removal. Meanwhile, the removable, washable liner absorbs sweat and keeps the helmet fresh. Finally, the extra-wide field of view improves awareness on both trails and roads.

Sizing

To determine which helmet size fits you best, measure the widest circumference of your head using a flexible measuring tape or piece of string; approximately 2cm above your eyebrows and ears as illustrated below. If your head measurement falls between two sizes, it is generally recommended to select the smaller of the two.

For maximum safety and comfort, take note of the following points when fitting the helmet (and securely fastening the chin strap):

• Helmet may take some effort to slide over your head, but should not be overly difficult
• Should fit snuggly around the crown of your head without creating uncomfortable pressure points
• The top padding presses on the top of your head
• The cheek pads press against your cheeks, so that your teeth touch the inside of your cheeks when opening / closing your mouth
• There should be no space to slide two fingers between the helmet and your temple
• Hold the helmet on either side and without moving your head, try to move the helmet up and down, and side to side. It should not be easy to move and you should feel the skin of your head and face being pulled
• Your eyes should be located in the center of the helmet's viewpoint
