I have the R1 helmet available, which is well-known. It is lightweight compared to some helmets. Made of carbon fiber with international certification. It includes an emergency cheek pad removal system. It has an air ventilation system to inflate the cheek pads. And an adjustable rear. There is also a shield against scratches and UV rays. With an anti-fog lens included with the helmet. The helmet is in new, unused condition. Good luck to all.
