Pinlock® Maxvision Fitting perfectly into the specially depressed area of the faceshield, the Pinlock® creates continuous air pressure through the compression force, which in turn stops condensation – and thus fogging – from occurring even when the temperature difference between the outside and the inside of the helmet increases. Kwikwick2® LINER:Very effective, hypoallergenic, removable, machine washable, and very soft and pleasant to the touch, the KwikWick2® lining of the new ScorpionExo® 2011 range is a real custom-made slipper for your head. New Ellip-Tec® Faceshield System Launched on the new Scorpion Racing Exo-2000 Air, the ELLIP-TEC® faceshield mechanism further improves the ease and speed of faceshield changes so unique to Scorpion. This operation can be done tool-less within 10 seconds, with the shield open. Wind tunnel designed to minimize wind noise at high speed, fitted with even more powerful springs to ensure optimum fit of the shield against the seal through the compression force, fully sealed and quieter, ELLIP TEC is also stronger to keep the shield in place in the event of a fall.Note Please note that as long as nothing else is written in the article description, all helmets that have a visor as standard will be delivered with a clear one, even if it is shown differently.
