Shoei X-15 Marquez Thai HelmetShoei developed the X-15 with technologies born from racing with one mission in mind, to make the fastest riders on the planet even faster. By designing and refining the X-15 helmet in their state-of-the-art wind tunnel facility, Shoei was able to reduce drag by 6.1% and lift by 1.6% compared to it's predecessor the X-14. The X-15 features a Multi-Ply Advanced Integrated Matrix Plus (AIM+) Shell, a six-ply matrix of fiberglass with lightweight organic and high-performance fibers to provide optimal impact-absorption, strength and elasticity. Packed in the X-15's shell is a multitude of features fit for a pro and ready to boost your performance, safety and comfort.Aerodynamic Shell Design Designed and refined in Shoeis state-of-the-art wind tunnel facility 6.1% reduction in drag and a 1.6% reduction in lift compared to the X-14 Over 150+ profile shape iterations enhance high-speed stability and reduce negative forces Rear stabilizer system, concave of the shell surface and pronounced edges on the top left and right sides of the helmet enhance aerodynamic performance Multi-Ply Advanced Integrated Matrix Plus (AIM+) Shell Six-ply matrix of fiberglass with lightweight organic and high-performance fibers provide optimal impact-absorption, strength and elasticity Four shell sizes Multi-Piece Multi-Density EPS Liner Optimized impact absorption thanks to varying densities of foam in key areas Precise placement of multi-density 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. material yields a more compact, lightweight design Strategically-located tunnels allow cooling air to travel unrestricted through the helmet Small channel in the front chin bar area strategically designed to guide and receive hydration systems (including the optional Shoei Hydration tube sold separately) Ventilation System Seven (7) closable air intakes and six (6) exhaust outlets Air intakes are strategically shaped and located to maximize airflow and negative air pressure suction to the rear of the helmet Ventilation tunnels in EPS liner enlarged to 10mm deep from 6mm in the previous model for superior ventilation Innovativecheek padcooling system by increasing the number of holes delivering refreshing air to the riders cheek area Field of Vision Revised eyeport trajectory from previous model increases the upper field of view by 5mm DKS-304 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. EVO lens system is 10% larger than its predecessor and improves lateral field of vision thanks to relocated pins outside of the eyeport CWR-F2R Shield & Base Plate System Distortion-freeface shieldthanks to Shoeis innovative 3D injection-molding process Protects against 99% of the suns damaging UV rays CWR-F2R 2D flat outside surface combined with 3D technology inside offers an aggressive look with optimized visibility Vortex Generators on the sides of the shield improve aerodynamics and reduce wind noise Center locking mechanism helps to evenly distribute shield forces across both spring-loaded base plates Exclusive two-stage shield locking system - center locking mechanism plus racing shield lock Trigger lock mechanism prevents the shield from detaching during an impact or crash 3D Max-Dry Custom Interior System II 3D Max-Dry Custom Interior System II is fully removable, washable, adjustable and replaceable Max-Dry liner material absorbs and dissipates sweat and moisture twice as fast as traditional nylon interiors Independently adjustable 3D center pad components can be replaced with optional thicknesses to customize the fit Each pocket-shaped pad has separate, removable layers that can be peeled away to further optimize the individual fit Patented angle adjustment mechanism allows you to change the position of the helmet by up to 4-degrees to increase the upper field of vision while tucked in extreme racing positions Surface area of the cheek pads has been enlarged by 16.5% from X-14 for a more secure and comfortable fit Emergency Quick Release System (E.Q.R.S.)Emergency Quick Release System that allows emergency medical personnel to easily remove the cheek pads from an injured riders helmetSafety Certifications Snell M2020R The Snell M2020R is a not-so-common "hybrid" helmet certification that is intended to enable the M2020 (also known as M2020D) safety certification in addition to EU ECE 22-05 and FIM FRHPhe-1 certifications. A very small minority of race-oriented helmets achieve certification with M2020R. certified ECE-22.06 ECE 22.06 is a helmet safety rating that extends and increases the testing requirements of ECE 22.05 (with 22.05 being a more modern, more comprehensive European alternative to DOT). With 22.06, 12 additional impact points are analyzed (now totaling 18) and impact speed is increased (from 7.5 to 8.2 m/s). Unlike DOT, every ECE helmet model must actually be tested by an independent lab before it receives 22.06 certification. certified DOT certified Note:Due to manufacturer restrictions, Shoei products can only be shipped to addresses within the United States.
