Most helmets adjust to your head.

Silvo is shaped for it first.

Built from thousands of custom-fit head scans, each size reflects real human variation — not simply scaled shells. A wraparound retention system distributes pressure evenly, while the self-adjusting rear cradle settles naturally into place.

The result is a fit that feels secure without overtightening — stable on rough roads, comfortable for long hours, and consistent under effort from the first ride.

Silvo earned a 5-Star Virginia Tech Safety Rating through an adaptive approach to structural energy management.

Its 3D-printed hexagonal structure is engineered to manage both direct and rotational impacts within the helmet itself — using tuned crumple zones, controlled shearing, and a reinforced internal structure to help dissipate energy across a wide range of real-world impacts.

Protection that’s designed into the structure — not added on.

Long climbs. Hot pavement. Midday sun.

Silvo keeps air moving across your scalp through an open internal structure and suspended fit system that allows heat to escape naturally. A central airflow channel and open-cell geometry help maintain steady ventilation without excessive bulk or insulation trapping heat.

The result is more consistent cooling across changing conditions — helping you stay focused, composed, and performing at your best from start to finish.

Designed with reinforced edges and tighter manufacturing tolerances to help maintain its shape, fit, and performance over time — without adding unnecessary weight or bulk.

Manufactured in the USA with close control over materials and process, Silvo reflects a commitment to thoughtful construction and long-term ownership.

Because the best helmet is the one that continues to feel right, ride after ride.

Silvo brings KAV’s data-driven design philosophy into a ready-to-wear helmet that ships in days — not weeks.

No custom lead times. No extra steps. Just intelligent fit, five-star protection, and adaptive performance — arriving when you’re ready to ride.

Smart design. Ready to ride.

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.

Responsive Exterior Structure

Silvo shifts rotational energy management outward through engineered structural slotting built directly into the outer hex lattice.

By allowing the structure to respond earlier during angled impacts, Silvo helps manage rotational forces before they travel deeper into the helmet.

Structural Energy Management

Traditional foam compresses uniformly.

Silvo’s 3D-printed structure is engineered to deform differently depending on how and where impact occurs — helping distribute energy more intelligently across the helmet.

Reinforced Where It Matters

Beneath Silvo’s responsive outer structure is a densified internal architecture designed to maintain protection through a wide range of real-world impacts.

The result is a helmet that balances controlled exterior response with a stable, reinforced internal core.

Tuned for Real-World Impacts

Real crashes rarely happen in a straight line.

Silvo’s variable geometry and directional slotting are designed to help the structure compress, shear, and dissipate energy across a broader range of impact scenarios — without adding unnecessary bulk or layers.
