This is Grex's new crossover based on the solid Nolan N43 Air model, which has become an icon in recent years, so much so as to also be appreciated by a number of Hollywood stars. The G4.2 PRO carries the much-appreciated technical characteristics of its Nolan counterpart, and continues the legacy of the G4.1 PRO, enriching it with a high-performance upper ventilation system and N-Com (ready for).
