Well if those creatures wore a helmet it would likely look something like the NEXX SX.100R Abisal Full Face Motorcycle Helmet. Thanks to many hours spent in Aerodynamic studies and wind-tunnel tests the SX.100R?s special shape offers a relatively lightweight helmet, with a sporty design that optimizes both stability and soundproofing at high speed. The SX.100R is equipped with a double-blade air spoiler at the rear, designed to optimize aerodynamic performance and reduce turbulence at high speeds. The large upper vent and chin ventilation system allow a large volume of cool-air to enter the helmet. In turn, the dual EPS Liner integrates an innovative air chamber: this allows a truly breathable helmet, with optimum exchange of warm, humid air with incoming cool, fresh air. The new SX.100R interior offers a snug fit and more effective ventilation around the entire head contour for maximum comfort and distraction-free in high speed riding. All interior parts, including the thick neck roll, are removable, skin friendly (Antiallergenic and Antibacterial properties) and made from soft touch X-Mart Dry fabrics that keep the interior cool, dry and comfortable. Quick release visor mechanism; makes changing visors extremely simple and quicker than never (less than 8 seconds) and tool free. The inner sun visor operates via an external ergonomic button, easily handled with gloves, filtering out 99% of UV light.
