We love the Freejump Voronoi Carbon Helmet for the abundant safety features as well as the maximized comfort and breathability! Incomparable next-generation protection.  
This is for the Helmet Shell ONLY - you can find the right liner for your helmet here: Voronoi Helmet Liners

The VORONOÏ CARBON is the riding helmet that combines the ultimate in new-generation protection, combining carbon, in-molding, and temporal protection.
Carbon: The outer shell of the VORONOÏ CARBON is made of carbon fiber, a high-tech material whose structure of layers of interwoven fibers offers exceptional impact resistance.
In-molding: A sheet of polycarbonate is overmolded over the inner shell, adding a protective barrier between the outer shell and the EPS shell.
EPS shell: the use of a carbon outer shell and in-molding technology allows the use of a particularly absorbent low-density EPS foam inside.
Temporal protection: the VORONOÏ CARBON is the first riding helmet with temple protection, reducing the risk of concussions in the most fragile part of the skull.
Enhanced security.
The temporal protection of the VORONOÏ CARBON helmet protects the temples and reduces the risk of concussions in this particularly vulnerable area. In fact, the temporal region is responsible for 80% of serious brain injuries. Behind the temporal bone is the meningeal artery, and the slightest trauma can damage this artery, causing a hematoma that compresses the brain cells, leading to serious after-effects or even death. The VORONOÏ CARBON helmet is the only helmet designed to specifically protect the temporal area.
The VORONOÏ CARBON temporal protection is designed to be easily assembled and disassembled using a screw system.
Safety first.
Our desire to develop the first riding helmet for better protection of the temporal area comes from an observation: each year in France, more than 150,000 head injuries require a trip to the emergency room, around a quarter of which are due to accidents. sport or leisure. These traumas are explained by the fragility of the brain and the thinness of the skull. The temporal area is responsible for 80% of serious brain lesions.
Temple protection reduces the risk of concussion on the most fragile part of the skull, the temporal area. Indeed, behind the temporal bone is the meningeal artery. The slightest trauma can damage this artery, forming a hematoma and compressing the brain cells, leading to serious after-effects or even death. The VORONOÏ CARBON helmet is the only one to take into account the temporal area, absorbing and distributing the shock wave over a large area to reduce the risks.
Tested since the work of the WG11 working group (Work Group 11), protection against rotational impact is perfectly assured, without additional artifices, the supposed advantages of which have never been demonstrated by independent laboratories, including the Virginia Tech Lab.
Safety, comfort, and lightness.
The internal shell of the VORONOÏ CARBON is made from one of the most absorbent EPS (expanded polystyrene) foams on the market. An integrated rib (between the upper part of the outside upper shell and the lower temporal part) reinforces the structure and offers crush resistance well above standards.
FREEJUMP was inspired by the technologies used in bicycle and ski helmets by integrating a polycarbonate sheet directly over the EPS foam. This In-molding technology, combined with the carbon fiber outer shell, offers exceptional impact resistance thanks to this three-layer construction. The interior lining is designed with high-quality Italian fabric to maximize comfort, breathability, and head support. It is removable to wash (wash at 30°C/86°F and natural drying) to ensure comfort and hygiene. The VORONOÏ CARBON helmet is extremely light for unparalleled comfort when worn over time: +/- 500g without the lower temporal protection with lining and long visor, +/- 600g with the lower temporal protection.
Design and ventilation.
Inspired by the distinctive geometric pattern that gave the helmet its name, the two vents (front and rear on the outer shell) are designed to optimize airflow to provide exceptional thermal regulation. The Voronoï pattern, with its irregular geometric cells, creates a unique and captivating aesthetic reminiscent of dragonfly wings. Each cell of the Voronoï pattern is carefully positioned to maximize strength and airflow through the helmet, optimizing safety, ventilation, and breathability. The internal shell of the VORONOÏ CARBON includes 20 vents, maximizing ventilation. The interior lining is equipped on the front with an ABS half-moon (clipped on the front edge of the interior shell), embellished by 2 openings directing the air flow as it enters the helmet.

The Voronoi helmet is available in three shell sizes: Small, Medium, and Large. Find the right liner for your helmet here: Voronoi Helmet Liners
