The fabrics used for the production of the helmet are currently the most efficient in terms of safety: prepreg carbon fibers woven in a specific way combined with a nomex honeycomb structure. The comfort that comes from the reduced volume and anecdotal weight of NACA® helmets improves the field of vision thanks to a visor close to the face and better penetration into the air.
These two safety aspects will allow you to discover the road in a different way, whatever your style of motorcycle!

A shape designed thanks to wind-tunnel tests for an optimal air penetration.
UFO has been able to combine a neo-retro look and aerodynamic performance. The back of the helmet is partially flat to reduce turbulences. The front ventilation of the helmet is a NACA® air intake in order to have the best performance with the least possible resistance.
