Shell Shell produced in ADT-advanced, a mix of thermoplastic resins with high resistance to crashes. NF-R shell is produced in two sizes: M and L. Protective Polystyrene Internal polystyrene liner realized in two sizes (M and L) to obtain a better ergonomics and a variable density. This characteristic allows a gradual and progressive absorption of the energy produced by the impact. Visor The visor of NF-R is PC injected, antiscratch, optic in class 1 with variable thickness. The hooks and rotation system allows the visor removal without tools. Ventilation Internal Polystyrene liner was studied to work in symbiosis with the air intake on the external shell. Particular channelings, obtained on polystyrene, allow to air flow intake an optimal ventilation into the helmet and a quickly exhaust of the hot air. Cheeckpad The cheek pads and the internal comfort shell can be removed, washed and replaced. They are made of precious bielastic fabric with specific fibers coupled with sponges with open cells for the best air flow in order to keep fresh and dry. Strap The retention system is equipped of micrometric buckle. Pinlock NF-R is equipped with PINLOCK Max Vision lens included. Note Please note that as long as nothing else is written in the article description, all helmets that have a visor as standard will be delivered with a clear one, even if it is shown differently.
