Rhoan stands among the fastest helmets on the market, within 0.001 CDA, or ~1 watt at 40km/h—while delivering airflow, cooling, and comfort they can’t touch.

The Rhoan earned a 5-Star Virginia Tech Safety Rating through a ground-up reengineering of impact protection.

At its core is our Hex Honeycomb Structure 2™ — a dual-density, 3D-printed lattice with independent hexagonal cells that deform asymmetrically to manage both linear and rotational energy.

This architecture eliminates the need for traditional slip-plane systems by integrating rotational management directly into the structure, resulting in lower weight, improved ventilation, and uncompromised real-world performance.

A 1°C rise in core temperature can reduce performance by up to 1.5%.

The Rhoan is made from our proprietary PolyCarbon Composite™ that wicks heat 8x better and cools 2x faster than standard EPS foam—helping you delay thermal fade and hold watts longer.

The Air Fit Suspension and HexFlow™ Rear Exhaust work together to create full-helmet airflow. Heat is actively pulled away from your scalp—maintaining focus, control, and comfort, even on the hottest days.

Our next-gen Hex Honeycomb Structure 2™ acts as a thermal scaffold, channeling air through its open-cell design. It improves both impact absorption and heat dissipation without adding weight or bulk.

Designed and manufactured in the USA using a net zero production process—delivering innovation, sustainability, and performance without compromise.

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.

Richard. _ 12/30/24

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.

Lane. _ 12/18/24

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!

Claudia G. _ 11/06/24

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.

John M. _ 10/30/24

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

NOT JUST A COLOR — A STATEMENT RETURNS

Hi-Vis orange is back and brighter than ever. Engineered to amplify contrast and visibility, it reflects more light across any environment—urban streets, mountain roads, or dusk rides—so your presence is unmistakable from every angle.

SUPERIOR CONTRAST & FLUORESCENCE

The Rhoan: Hi-Vis utilizes advanced fluorescent technology, which absorbs light during the day and stays brilliantly visible even in low-light settings.

PROTECTION YOU CAN SEE

Awarded a Virginia Tech Five-Star Safety Rating, the Rhoan: Hi-Vis showcases our advanced Hex Honeycomb Structure 2™ through its exterior semi-transparent shells—a visual reminder that safety can look just as striking as performance feels.

The whole process from order to delivery of your custom helmet takes as little as two weeks + shipping.

The Rhoan earned a 5-Star Virginia Tech Safety Rating through a ground-up reengineering of impact protection.

At its core is our Hex Honeycomb Structure 2™ — a dual-density, 3D-printed lattice with independent hexagonal cells that deform asymmetrically to manage both linear and rotational energy.

This architecture eliminates the need for traditional slip-plane systems like MIPS, by integrating rotational management directly into the structure, resulting in lower weight, improved ventilation, and uncompromised real-world performance.

Every helmet is custom made so even for the same circumference, your head shape can change the size by +/- 20 grams. However someone who is in the middle of medium (~57.5 cm circumference) can expect their KAV Rhoan helmet to weigh 300grams.

Our helmets are engineered with our proprietary Hex Honeycomb Structure 2™ which has the most efficient energy absorption to weight ratio or crumple zone design to redistribute energy & force upon impact.

Yes, the Rhoan features a rear ratchet mechanism built into them that allows 8-10mm of travel ensuring both a snug fit as well as giving your custom helmet a bit of play to account for the winter season or a new haircut.

"This is the best helmet I’ve ever owned. Well worth the wait. Hardest part was adjusting the strap placement around my ears. Now all I have to do is put it on my head and clip the strap. 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."
