Portola: Kaze

30-Day: Full Refund Guarantee

At KAV we fit different. Our custom fit bike helmets are made-to-order for you. If after 30 days of receiving your 3D printed bike helmet it’s not the best fitting helmet you’ve ever experienced we will give a full refund.

100% Crash Replacement Program

Our crash replacement program has you covered. You receive a one-time 100% replacement of the same model during your entire five year warranty. Just send your helmet back to us so we can analyze it and make improvements if needed.

5 Year Warranty

We have the best warranty in the industry. Other brands offer one year limited coverage and say you need to replace a helmet every three years, not us! Every 3D printed bike helmet is covered by a five-year warranty from the date of purchase.

How #wefitdifferent


No MIPS Necessary:

3D printing enables us to create a crumple zone that can compress almost 3x more than traditional helmets.

This structure allows the helmet to shear when needed or compress when needed based on the impact eliminating the need for both MIPS or an extra layer.

Custom Fit & MADE for you

Every KAV helmet is made to order and begins with your seven unique measurements. Each helmet begins with a one-on-one fit session to take your exact measurements, and is 3D printed to order in Redwood City, California.

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


Whereas most companies outsource all their testing, we have our own test lab and utilize a network of 3rd party test labs to verify the results.

Without the constraints of styrofoam, we use our KAV PolyCarbon Composite, Hex Honeycomb Structure, and fit pad system to holistically reduce linear and rotational impacts by 25% more than the U.S. CPSC safety standards.

Why doesn't the KAV helmet have MIPS?

Why Hex and why it matters.

Is a 3D printed bike helmet safe?

What if I want to wear a cap or cut my hair, will my custom fit cycling helmet still fit?
