The Portola: Kaze is 3D printed and customized to your exact measurements. 

Building on the first-generation Portola, the new Kaze delivers 17% better ventilation, a 10% reduction in weight, and a reimagined sweat management system, all whilst being 25% more impact resistant than the U.S. CPSC safety standards.

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

     

  • The KAV PolyCarbon Composite material naturally wicks heat 8x better than EPS foam

     

  • Net Zero Emissions Manufacturing

     

  • Made in the USA

Custom in Four Steps:

Step 1: Your custom helmet begins with a Fit Kit which you receive either after purchase of the Portola or you can order a complimentary one via the Fit Kit page on our site.

Step 2: We schedule a virtual one-on-one fit session to establish your custom helmet measurements. The virtual fit session itself takes about 15 minutes. During the session we’ll take 7 measurements.

Step 3: The next day, we'll ship you a mold of your head. The mold reflects the fit of the helmet and gives you a chance to make any adjustments if you need to.

Step 4: After we get your thumbs up, we’ll make your helmet. No pressure points or dials to adjust. The best, Made For You

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

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. _ 12/30/25

As someone who was always on the smaller side of a medium, but too large for a small, I had to put up with helmets that looked oversized and needed to be ratcheted down to stay put. This one fits so well I don’t even need the ratchet.

Lane. _ 05/13/26

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. _ 11/06/25

I always stick to the same couple of helmet brands because I know they fit. I’m hesitant to try something new if I can’t try it on but that wasn’t the case with KAV. The process was easy and the helmet fits perfectly!

I finally have a helmet that doesn’t look ridiculous on my head.

"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."
