Speedy Security

The Oakley ARO5 Race was designed for peak performance and maximum breathability on the road. With results in mind, ARO5 Race features an aerodynamic and ventilated design that significantly increases airflow throughout 19 ventilation ports.

Lighter than its predecessor, ARO5, ARO5 Race provides the advantage needed to overtake the pack. Combined with additional technical advancements in optics integration, comfort, and protection, ARO5 Race is ready to go fast.


  • FIT: A BOA 360° fit system includes an adjustable dial that delivers a more secure fit and maximizes safety. Overall improvements to the shell shape ensure ARO5 Race sits lower on the head for better balance, while fitting more naturally to the contours of your head.
  • LIGHTWEIGHT: ARO5 Race is lighter than its predecessor, the ARO5, achieved through a newly designed shell and other internal modifications.
  • PROTECTION: The Mips® Air safety system is a helmet-integrated, low-friction layer designed to decrease rotational motion to the head, helping to reduce the harmful forces that might otherwise impact the rider's head.
  • VENTILATION: ARO5 Race features newly designed front and top ventilation ports to significantly increase airflow and breathability. There are 19 vents in total across the top, side, and rear sections.
  • LINING: The Ionic+™ Antimicrobial liner is sweat-activated, keeping things fresh, and odor under control.
  • EYEWEAR STORAGE: Front vents provide riders with a go-to spot to easily stash their eyewear. Unobtainium® grippers hold eyewear stems in place, while cutouts in the foam on the interior of the helmet prevent the stems from injuring the wearer's head in case of impact, creating a simple and intuitive eyewear storage space for riders.
  • DESIGN: ARO5 Race features a branding badge with an Iiridium® coating, mirroring the Prizm™ lens colors seen in Oakley eyewear. Each badge color is unique to the color of the helmet, with all celebrating Oakley's eyewear heritage.
  • Helmet Travel Bag and Oakley Decal Included
  • Small (52-56cm) / Medium (54-58cm) / Large (56-60cm)

Comfortable helmet once I removed the sweat guard
by BikerJon

This helmet was extremely uncomfortable out of the box, had to turn around and head home after an hour due to the headache it gave me. The main issue is the sweat guard is really hard material and creates a lot of hot spots. I almost gave up on the helmet but I tried changing the sweat guard to a normal cloth padding from an old helmet and that fixed the issue. It's actually super comfortable and I'm really liking it. Looks good, fairly light, and the grippy glasses holder works well. Think Oakley needs to rethink the sweat guard though.

New design improves air flow but not comfort

I had the previous version of this helmet and was excited to see they improved the air flow. Unfortunately there are a couple places the front pad mount to the helmet that hit right on my temples and make the helmet very uncomfortable wearing more than an hour.
