The Impact Eurosport helmet is Snell 2010 Certified. The Eurosport helmet was engineered with the open cockpit racer in mind. Impact understands that it's hard to drive if your head is being buffeted around, so they placed an airfoil at the rear of the Eurosport. The airfoil reduces turbulence around the helmet and helps you focus on driving, not fighting to keep your head straight.Made in the USA!
