The Nexx X.G30 is a great helmet for riders who like a vintage look paired with modern safety and technology features. It's inspired by the classic jet helmets of the mid sixties. Depending on the sub-model, you'll either get a carbon fiber shell or an X-Matrix 2 shell. The X-Matrix 2 shell combines 6 different layers, and provides world class penetration resistance, and high energy impact management. If purchased in the USA, the helmet is DOT and ECE 22-06 homologated. The interior pads are extremely comfortable, dry super-fast, and can be removed for washing. The double d ring strap is tried and tested for it's reliability. In order to get an accurate, comfortable fit the NEXX X.G30 uses 3 different shell sizes. A windscreen, drop down visor, and peak are either optional or included depending on which sub-model you choose.
