The Shark Spartan Priona full face motorcycle helmet in white blue red is designed with a double back spoiler for streamlined aerodynamics and stability at high speeds and has SHARK skin peak side fastenings: passive reduction of aerodynamic noise. This is also ready for Shark's patented Sharktooth communication system. The clear anti-scratch visor has an autoseal system which flattens the visor onto the helmet, giving better soundproofing and seals the helmet (against water and cold) as well as having a quick release visor system. The Spartan comes with 2 shell sizes further helping the aerodynamics from this compact helmet. The Aegis micro-tech interior is anti-bacterial as well as removable and washable for added comfort and is suitable for glasses wearers. An internal sun-visor as well as a breath guard are handy additions along with a Pinlock insert and a double D ring strap closure system for added confidence.
