The AGV K5-S Vulcanum outer shell is engineered from a carbon fibreglass mix, ensuring it is extremely strong and light, whilst the integrated spoiler ensures aerodynamic performance. The anti-scratch clear polycarbonate visor gives 100% protection from U.V. rays and has an Anti-Fog Pinlock insert. The Visor ratchet system can be customised; choose from Touring, Race and City by changing the toothed mechanism, and the XQRS (Extra Quick Release System) gives tool-free removal and replacement of the visor in seconds. Internally the AGV K5-S has a four-density E.P.S. inner shell for impact absorption, and the removeable inner liner is fashioned from high-performance, moisture-wicking fabrics with no stitching in any sensitive areas for a very comfortable fit. Comfort is further enhanced with A.G.V.'s I.V.S. (Integrated Ventilation System); the vents are actually hollowed into the shell and direct air directly onto the rider's head. The 5 front air inlets, 2 rear extractors and micro opening de-mist visor mechanism are all fully adjustable to ensure your head is at its happiest. An internal drop-down sun visor, Double D retention system, removable nose guard and chin wind protectors add to the high specification of this A.G.V. helmet.
