Jet motorcycle helmet modulates Grex G4.2 PRO
Cod. G42000
It is the new Grex crossover built on the solid basis of the Nolan N43 AIR model, icon of recent years, to the point of being appreciated by numerous Hollywood stars. G4.2 PRO confirms the already appreciated technical characteristics of the counterpart produced Nolan and collects the legacy of G4.1 PRO, enriching itself with the performing superior ventilation system and the N-Com predisposition.

TYPE-APPROVAL P/J
The helmet is approved in the double P/J configuration, as it has a removable protective chin guard that passes the homologation tests required by the UN/ECE standard for integral helmets.

ULTRAWIDE VISOR
The large surface area of the visor, resistant to scratch (S/R – Scratch Resistant), makes possible a greater view, even lateral, thus ensuring maximum driving comfort and increasing active safety. It is also able to protect the pilot's face from water and wind, while ensuring adequate air circulation inside the helmet, if the helmet is used in jet configuration.

INTERNAL VISOR RESISTANT TO PINLOCK FOGGING®
Available as an accessory and with silicone profile (FSB – Full Silicone Border). The exclusive adjustment system adopted by Nolangroup, patented, allows you to adjust the tug of the visor (Pinlock®), acting from the outside of the visor and without the need to disassemble the visor itself.

SUNSCREEN (VPS) WITH UV 400 PROTECTION
Located inside the helmet, it is printed in LEXANTM* and includes S/R (Scratch Resistant) and F/R (Fog Resistant) treatment. It offers UV protection up to 400 nanometers and can be easily disassembled, when not necessary or for maintenance and cleaning. * LEXANTM IS A TRADEMARK OF SABIC

VENTILATION SYSTEM
The exclusive ventilation system, complete and extremely effective, takes advantage of three different air flow management, through a front outlet, two upper sockets and two rear extractors that allow an optimal recirculation of the air inside the helmet. A slit located at the bottom of the visor also contributes to ventilation in the mouth area, limiting the fogging and condensation on the visor itself, if the helmet is used in full configuration.

COMFORT INTERIOR PADDING" AIR TOP COMFORT"
Completely removable and washable, it has been renewed in structural and aesthetic terms. Decisive improvement of comfort in the ears area, facilitated fit and an aesthetic in line with that of the latest Grex.

N-COM PREDISPOSITION
