ARAI QUANTUM ITALY UK Arai The New Quantum has safety technology from the GP and uses the same triple layer shell construction with a 'Hyper Ridge', which is basically a wider base, for added safety and ease of getting the helmet on and off. The vents have been updated and improved and the visor is 5mm wider on each side the same as the GP for better peripheral vision and comes complete with pinlock antifog insert. The fully removable lining is made of a Dry-Cool material for improved wicking and comfort. Like the GP the Quantum also features Arai's emergency release cheek pads.
