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.

BUNDLE: HELMET + PUMP
The Ventete aH-1 ships with the Ventete x Fumpa Pumps Mini.
Ultimate protection. Perfectly portable.
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, Ventete’s patented pneumatic structural system responsively absorbs impact forces in the event of a collision. The inflated structure extends the impact duration compared to conventional helmets, slowing and dissipating force over a longer period of time.
In a third-party study carried out by HEAD Lab at Imperial College London, the Ventete aH-1 was noted to provide a 44% reduction in overall linear risk compared to the best performing conventional helmet tested.

TRANSFORMS IN 30 SECONDS.
Always within reach. The Ventete aH-1 helmet deflates to 10% of its inflated size to take up less space than a laptop.
Included USB-C rechargeable pump and on-helmet pressure indicator make inflation and deflation simple.
ENHANCED ROTATIONAL IMPACT PROTECTION.
Developed in collaboration with RHEON™ Labs, the aH-1 internal liner features a non-newtonian superpolymer. The liner is soft and flexible in its natural state to adapt to your head for a superior fit. On impact, the material stiffens dynamically, shearing in multiple axes to dissipate energy and protect the head.
Working seamlessly with Ventete’s pneumatic structural system, the liner effectively controls and reduces rotational forces—the primary cause of traumatic brain injuries 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.
