Oakley ARO5

The Oakley ARO5 is a streamlined helmet for the discerning cyclist who seeks an aerodynamic advantage without compromising comfort or ventilation.

Maximizing aerodynamics, the helmet's wide channels at the front reduce drag while moving air is grabbed from the rear scoop and channeled to the narrow rear exhaust vents.

Instead of simply adding MIPS® straight into the helmet, the baseline design for the ARO5 integrates MIPS® fully. This intentional design offers better comfort by distributing pressure points on soft brow pads and crown pads when tightening the helmet down. The Boa® 360 Fit System was chosen for this helmet to provide the effortlessly integrated eyewear dock. With the low-profile nylon webbing that makes up the 360° tightening system, eyewear can be stowed without getting snagged and caught in the helmet, unlike other fit systems.


  • An integrated eyewear dock to securely stow your shades and keep them handy for quick and easy access
  • BOA® 360 Fit System has a soft textile feel and flexibility. The TX1 Lace lies flat against your head, allowing for seamless eyewear compatibility
  • X-STATIC®l BROW PADDING: X-Static® harnesses the power of silver to create a powerful technology that inhibits the growth of bacteria on fabric, eliminating odor for the life of the product. Also ships with a secondary set of pads
  • MIPS® INTEGRATION: The MIPS® Brain Protection System is a helmet integrated, low friction layer designed to reduce rotational motion transferred to the brain during an impact
  • Helmet Travel Bag and Oakley Decal Included
  • Small (52-56cm) / Medium (54-58cm) / Large (56-60cm)

    Lite and pleasing to the eye

    Bought it to replace a Catlike helmet. Similar venting qualities but better adjustability.

    Great Helmet

    I have been using this helmet for a month now and I love it! Specially the option to have a silicon strap in the front instead of the usual foam. I sweat quite a lot so this avoids the drops falling into my sunglasses. If you prefer the foam you can just take it out and put the foam that is included. Another thing that I really liked was the nice sleeve included to protect the helmet when travelling. Great purchase!

    You don't see too many of these helmets out there, but it is definitely a nice one. Love the colors as well. Despite being pretty aero it still has great ventilation. They do advertise that this holds glasses well, but when I try and put my Jawbreakers in there, they always fall out, no matter if I put them in right-side-up or upside-down. Other than that, great helmet.
