The original Shark Skwal LED Motorcycle helmet was the 1st helmet with an LED light system, and Shark has improved on this with the Skwal 2. For this latest version, Shark has revised the helmet's aerodynamics to make it more stable and quieter and increased the brightness of the LEDs. The Shark Skwal 2 Hallder full-face motorcycle helmet has a lightweight injected thermoplastic resin polycarbonate outer shell for rigidity and shock absorbency. Three pairs of green LEDs are built into the helmet shell - one above and another below the visor on the front, with the third set just below the rear spoiler. These LEDs are powered by an integrated battery pack that's easily charged via a USB charger. The clear visor comes with a Pinlock Max Vision anti-fog insert. It has Shark's auto-seal visor mechanism providing an excellent seal with the helmet's rubber gasket, preventing water ingress. An internal drop-down sun visor enhances the rider's comfort, and the interior is removeable and washable. Ventilation is provided by adjustable chin and forehead inlet vents. The Shark Skwal 2 is also pre-prepared for Sharktooth, Shark's wireless intercom system and has a micrometric retention system. The Shark Skwal 2 series of motorcycle helmets are available in other colours and graphics.
