HELMET SIZING
CIRCUMFERENCE
(CM)
HOW TO MEASURE THE CIRCUMFERENCE OF YOUR HEAD
Wrap a soft measuring tape around the widest part of your head and note the length. If you don’t have a soft measuring tape, you can use any charging cable, string, or rope and lay it against a ruler. Don’t have a ruler? Try using printed pieces of paper with known length.
BETWEEN SIZES?
If you’re between sizes, we recommend sizing up. You'll be able to tighten the helmet for a perfect fit using the retention strap system.

Included USB-C rechargeable pump and on-helmet pressure indicator make inflation and deflation simple.
SWISS MADE SAFETY.
To best protect your head, The Ventete aH-1 is made in Switzerland for exquisite quality of manufacture and trusted safety performance.
Fully Certified to EU and UK (BS EN 1078:2012 + AI:2012) testing standards.
Refined over years of comprehensive impact testing and independently assessed by HEAD Lab at Imperial College London, Ventete’s patented pneumatic structural system responsively absorbs impact forces in the event of a collision. Non-Newtonian RHEON™ padding enhances protection against rotational motion, the leading cause of traumatic brain injury in accidents.
ENGINEERED TO KEEP YOU COOL.
The air structure of the Ventete aH-1 is less insulative than conventional foam helmets, keeping you cooler by allowing heat to dissipate with superior efficiency into the surrounding environment. Linear internal channels draw unbroken airflow over the whole head.
Holistic material innovation engineered to keep you comfortable while you ride.
