Precision Fit from anywhere
Step 1: Measure
Personalize and order your helmet and we'll send you a fit kit and help you take your measurements.
Step 2: Analyze
Our machine learning algorithms derive your head shape and generate the dimensions for your helmet.
Step 3: Fabricate
Your helmet is precision 3D printed, hand assembled here in Redwood City, CA and shipped to you.
Protective
I want the safest helmet possible
Exceeding CPSC certifications, a safety first approach to engineering and space age materials make a helmet with unparalleled safety.
Lightweight
I like to forget I'm wearing a helmet
Our specially formulated TPU cuts 20% of the weight while being 3x stronger than foam. The result is a sub 300g helmet in every size
Aerodynamic & Cool
Help! I sweat a lot!
A custom fit helmet has a smaller frontal cross section reducing drag. And unlike other helmets that have to use closed structures to optimize the drag coefficient, there is no need to make a trade-off between aerodynamics and ventilation.
Durable
I'm tired of replacing my helmets all the time
Unlike foam that dents and degrades over time, the TPU from the KAV helmet has its roots in hockey so it can take any tumbles off the bike and protect riders when they need it most.
Adjustable
Sometimes I wear a cap with my helmet
We made sure that our helmet can accomodate haircuts, cap, no cap, or whatever you want to throw on that day.
Made in the USA
I want to support our economy
The R1 is designed, engineered, and printed in the USA. We pride ourselves on our made to order system that reduces waste and is kinder to the planet.
Guaranteed to fit
Try out our helmet for 30 days and if you experience any discomfort, talk to us directly and we'll make it right.
5 year warranty
Our helmets are engineered to support you in every situation. Send us back the helmet so we can make them even better, and you'll get a new one.
Crash replacement
Last thing you need to worry about after your crash is your helmet. Send us back the helmet that saved your life, and we'll ship a new one at 50% off.
