30-Day Risk Free Trial

At KAV we fit different. This is not a keep it in the box / as new return policy. Our custom fit bike helmets are made-to-order for you. We want you to go out and ride hard in your helmet. 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.


Here’s a closer look at the KAV Portola Helmet 👀

Amazing Helmet, Easy Process
I just received my KAV helmet a few days ago and have been on a couple of rides with it. It's completely different than any other bike helmet I've had.

While all KAV helmets are customized to your exact measurements, your preferred size may change over time. From haircuts, to skullcaps, to a simple adjustment of fit preference, we designed the KAV Portola Helmet to change and grow with you. Our custom pads allow for 4-6 mm of adjustment from your original fit - no dials, no straps, no headaches. 



Intertek Laboratories confirms the KAV Portola Helmet to be at least 25% more impact resistant than the national CPSC safety standard. Our proprietary carbon fiber-reinforced copolymers are optimized for both rotational and linear forces.
