Shoei GT-Air 3 Nile HelmetThe Shoei GT Air 3 Helmet represents the next generation of touring helmets. Starting in the wind tunnel, the sleek Advanced Integrated Matrix fiberglass shell showcases a balance of strength and lightness. Using "Silent Ride Engineering", the aerodynamic ride of the GT Air 3 are further supported by the 3-D Max-Dry cheek pad and liner system, included chin curtain and optional, shell-integrated SRL3 Bluetooth system (sold separately).The GT-Air 3 ships with a clear, fog-resistant CNS-1C face shield with Pinlock A Pinlock lens is made to enjoy a fog-free ride. It is based on two key principles to ensure a fog-free vision. The moisture absorbing surface of the lens effectively attracts and stores water molecules, while the airtight seal creates a thermal barrier together preventing condensation of the visor. The system is kept in place by positioning the lens between two adjustable pins, making Pinlock the number one anti-fog solution for helmets. lens insert included. An internal drop-downQSV-2 sun visor provides wide, full spectrum coverage from harsh solar rays.Versus the model that it replaces, at speed the GT Air 3 sports an 11% decrease in lift and - most importantly - a 6% reduction in frontal wind resistance over the GT Air 2. Tighten the micrometric A micrometric fastener is an adjustable fastener commonly used in helmets, pants, boots, etc. Also known as "micro ratchet" or just plain "ratchet fastener", the system uses a spring-loaded ratchet mechanism that interlocks with an opposing strip of toothed metal or plastic. It is best known for its ease of adjustment - especially with gloved hands. In helmets, it takes the place of the classic double D-ring closure. ratcheting chin strap, hit the road, and go.The GT Air 3 is an unparalleled blend of sport, comfort and touring.Aerodynamic Shell Design: Shoei's top full-face touring helmet Revised gasket seal for even better protection from noise and weather intrusion Real world and wind tunnel testing to improve aerodynamic properties - exceedingriders feedback from GT-Air 2 predecessor Firmer shield detents to keep shield in place in every scenario Multi-piece EPS liner Expanded polystyrene (EPS) is a rigid, energy absorbing foam. In the helmet industry, EPS is the most common means of energy management to protect the brain. Generic EPS is often referred to as Styrofoam (a trademarked name owned by the Dow Chemical Company). Premium helmet producers utilize multi-density EPS liners to balance comfort, safety and performance. enhances impact absorption and ventilation Molded air spoiler reduces drag and lift as well as diminishes pressure on the riders neck while riding at speed Integrated comm systembase accepts the Shoei SRL3 Bluetooth Communicator by Sena Advanced Integrated Matrix (AIM): High performance fiber materials combined with elastic organic fibers to create a shell structure that is ultra-lightweight, rigid and resilient Three shell sizes: XS-MD, LG, XL-2XL CNS-1C Shield System: CNS-1C three-dimensionally curvedface shieldis both wider and taller than the shield it replaces Includes CWR-1 Evo Pinlock Anti-Fog Lens insert Dual-ridge window bead increases contact with the shield to reduce wind noise Scratch-resistant shield coating 99.9% protection from harmful UV A&B rays Sun Shield Visor System: Built-in QSV-2 sun shield gives riders instant relief from sun glare in one quick motion Visor meets ANSI Z80.3-2010 standard for non-prescription eyeglasses Large and easy to reach slider activates the 3D injection-molded inner sun shield Distortion-free shield blocks 99% of harmful UV rays Ventilation System: Redesigned upper air intake vent positioned to maximize air volume into the helmet interior Enlarged lower intake vent with filterreduces shield fogging and increases ventilation Upper and lower intake vents are easy to operate even with gloved hands Rear/neck vents allow for effective air exhaust Breath guard and chin curtain included Interior System: 3-D Max-Dry center pad and multi-layered, polyurethane foamcheek pads Chin curtain prevents wind entry and reduces noise Cheek pads are replaceable or removable for maintenance Eyeglass compatible interior E.Q.R.S.
