The GP-6S is designed with the sport driver in mind (hence the "S" designation). It uses the same shell shape as the GP-6 (PED) and state-of-the-art GP-6RC, along with the same wider eye port for increased peripheral vision. The single intake/single exhaust vents provide excellent ventilation performance. Check the entire list of features and we think you’ll agree: The only thing missing from Arai’s GP-6S is the higher price tag. Now Snell SA2015 certified, with the new M6 washer/nut installed at the factory. With the 6mm washer/nut installed, anyone can now easily install a variety of Head and Neck Restraint systems that use a 6mm bolt to their helmet. This helmet also comes with the FIA-8859-2015 certification sticker applied to the interior liner of the helmet.
