What People Are Saying

Very light and comfortable. I like the style and it was a very easy process to get fitted for this unique helmet.

KAV stands by their products. In October, I had a cochlear implant, which changed the dimensions of my fit. KAV offered me a significant discount, provided a re-fit to accommodate my implant. Not only an excellent NOVA product, but outstanding customer service.

It feels great throughout long rides and I even forgot to take it off after a ride recently! Do yourself a favor and order the perfect helmet - for comfort, safety, design, weight, and ventilation!

This is the best helmet I’ve ever owned. No more adjusting the back closure and looking in the mirror to make sure it is not crooked on my head. Fits perfectly every time.

I had the amazing opportunity to be able to purchase one of their 3-D printed helmets with custom coloring.

2x Larger Front Vents

Strategically placed lower on the brow to funnel cooling air directly to the forehead, where thermoregulation is most effective.

It’s not just about vent size—it's about vent placement that works with your physiology.

A Fit That Breathes

Our Air Fit Suspension System™ suspends the helmet off the head, eliminating pressure points and maximizing ventilation.

This all-around airflow helps reduce hot spots and maintain a cooler, more stable core temperature throughout your ride.
5-Star Virginia Tech Safety Rating

The Rhoan’s Hex Honeycomb Structure 2™ uses a dual-density, 3D-printed design that adapts independently on impact — absorbing energy from both direct hits and rotational forces.

This advanced structure eliminates the need for bulky add-ons, reducing weight while enhancing real-world safety and comfort.

Aerodynamics That Actively Cool

Engineered to harness the Venturi effect, the HexFlow™ Rear Exhaust accelerates air as it exits the helmet—pulling heat and moisture away from your head with every effort.

Working in tandem, the Air Fit Suspension System lifts the helmet off your scalp to create uninterrupted airflow throughout. The result: better cooling, reduced core temperature, and sustained power when it matters most.

Lock In. Ride On.

Redesigned and 3D printed for real-world use, the new sunglass ports make it easy to stow your shades mid-ride—and keep them secure, even over rough terrain. No slipping. No rattling. Just smart, ride-ready utility.
