Ventete aH-1
The world's first inflatable helmet — protection the size of a laptop. Crafted in Switzerland, the aH-1 swaps rigid foam for eleven connected air chambers, using compressed air to absorb impact 44.1% better than ordinary foam helmets, as independently tested by HEAD Lab at Imperial College London.
The helmet folds to under 4cm thick and inflates in 30 seconds through an integrated Clik valve — cushioned inside by custom RHEON™ padding that protects against both linear and rotational impact.
The RHEON™ padding was designed to not only achieve a high level of linear and rotational impact protection, but to adapt to the shape and surface of the head, allowing air to flow unrestricted, keeping the rider cool and comfortable during the day.
