Arai Quantum X Wave HelmetThe name Arai has been synonymous with quality and protective technologies since the beginning of their days and the Quantum X Spine Helmet continues to push the bounds, proving why Arai stands at the top.The Quantum series has been the go to helmet for riders with a more round headshape and this stays true with the Quantum X, thanks to its balanced length and slight additional width. With the simple installation of a Corsair X head liner, the Quantum X can even be converted to fit those with an intermediate oval headshape.The Arai Quantum X Motorcycle Helmet features a chin curtain that helps to block air intrusion from the turbulent air underneath the helmet, as well as increases negative pressure to enhance theexhaustventilation performance. The interior lining includes Arai's signature 5mm peel away ear pocket padding and ear pocket recess to accommodate communicator speakers.PB SCLC Shell: Peripherally Belted - Super Complex Laminate Construction shell Design combines multiple materials and techniques created internally by Arai that deliver both performance and affordability Shell has superb tensile strength due to a variety of carefully-positioned materials and light weight resin VAS Shield System: VAS (Variable Axis System) shield and side pods are exclusive to the Arai Corsair X Helmet Variable axis (moving pivot point) allows shield mount position to be lower than most helmets Dual function lever releases both the side pod and the face shield for quick and simple face shield removal VAS Shield Latch System: Captures and holds the face shield closed securely Provides a de-mist position to slightly crack the shield open Larger latch design allows for intuitive and seamless operation VAS V MV Shield: VAS MAX Visionface shield Provides excellent visibility in all seasons Includes clear anti-fog 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. insert Ventilation: QVF and QVR upper ventilation ducts offer adjustment and airflow performance Vents are easy to operate with gloved hands Arai's Proprietary Liner: Fully removable and soft interior liner andcheek pads Made from odor-resistant material which helps maintain neutral acidity levels close to human skin Adjustable temple padding to allow for a customized fit Neckroll is removable and has additional exhaust channels to remove interior heat Safety: Snell 2020 The SNELL Memorial Foundation is still largely considered the gold standard for helmet safety. SNELL M2020 certification uses the most aggressive anvil profile, known as an edge anvil, and demands a ridiculously low 275 g maximum energy transfer after two blows. SNELL testing is designed with the energy levels and safety requirements of the racetrack in mind, and this is reflected in the additional testing for characteristics such as stability and ease of removal in an emergency. SNELL technicians look for the weakest point in the helmet and target that point when testing. Technicians will strike multiple locations, testing until they are satisfied an accurate indication of the helmets energy-management ability has been attained. Also listed as SNELL M2020D. and DOT approved Cheek pads have the Emergency Release Tab feature
