3 different construction technologies currently exist to develop a helmet, each one possessing advantages and drawbacks.

1. Helmets with a rigid shell

Their injection moulded shells are extremely robust but relatively heavy. Energy produced from a vertical or lateral impact is absorbed through deformation of the shell. The helmet is fitted to the head using an internal cradle system made from webbing, which provides excellent air circulation but less stability for a relative amount of comfort. This type of helmet is used less and less for sports but is still very common in the construction industry.

2. Hybrid helmets

Their injection moulded shells are complimented by a moulded polystyrene liner. This hybrid process offers a good compromise. The impact is no longer absorbed by only the shell’s deformation. The expanded polystyrene disperses the impact’s force by absorbing energy. Nevertheless, lateral protection during a fall is compromised as the sides are not generally lined with polystyrene. This type of helmet is of particular interest to those who will subject it to intensive use thanks to its robust nature. It is highly suited to clubs, children and rescue organisations.

3. Polystyrene helmets

Their structure is made entirely out of moulded polystyrene which is protected by a thin layer of polycarbonate. This manufacturing process yields both a very light and reliable helmet in an impact situation. The thick layer of moulded polystyrene used throughout the entire structure allows the energy of an impact to be dispersed in all directions. However, the thin polycarbonate shell also renders it more sensitive to small knocks when in use. Ventilation is generally good and the ergonomics of the lining excellent thanks to precise adjustments of the cradle.



We designed comfortable fitting adjustments, with easy opening and closing of the buckle - even with gloves. With the helmet placed on the head, simply turning the rear adjustment dial easily adjusts the cradle system to your head circumference; ensuring a precise fit and stabilising the helmet’s position. All that remains is to clip the two magnetic parts of the chinstrap buckle together to centralise and secure the helmet to your head. A clever release mechanism on the chinstrap buckle allows you to unclip even with just one hand.

Impact absortion


For our hybrid helmets, as well as our polystyrene helmets, only raw materials that are of the highest quality are used so the polystyrene cells collapse to dissipate the energy as fast as possible in case of an impact, therefore better protecting the user’s head.



Large openings situated both at the sides and at the back of the helmet create air channels that stimulate circulation and venting.
