Arai Defiant Jolly Roger Helmet

The Arai Defiant was built for the upright riding position with its aggressive, integrated chin spoiler, designed specifically to guide wind around the neck and to improve the aerodynamic properties of the helmet. The Arai Defiant also features the exclusive FCS cheek pad system, a multi-density one-piece EPS liner, micro-fitting interior padding, pull down spoiler and a Dry-Cool liner material.

The Hyper Ridge Bumper circles the bottom of the shell both adding additional strength and also lowering the helmet's center of gravity, while flaring the helmet opening slightly to increase the ease of putting on and taking off. The Defiant uses Arai's the SAI Max Vision Pinlock Shield with Brow Vents and includes the Pinlock insert lens. The SAI Max Vision shield has been widened by 5mm left and right and offers one of the widest eyeports available for excellent peripheral vision.

Awesome Helmet and Graphics
I purchased the Defiant to replace my Arai XD-4. Once I saw the graphics on the Jolly Roger I new I had to have it. I love the graphics, the pictures online don't do it justice. For me the Defiant is quieter than the XD-4 and with all the vents closed up there is less air leaking through the helmet. With all the vents open it flows a ton of air, I can't wait to try it out this summer. The only downside to the helmet is the peripheral vision, the vision is a little narrow compared to the XD-4. After riding all day in the wind the Defiant is light weight, very comfortable and performs really well when I am riding my 2012 Concours. Overall the Defiant Jolly Roger is great helmet.

PROS: Airflow, Light Weight, Graphics

CONS: Vision Is A Little Narrow
