PLEASE NOTE THAT HELMETS ARE NON-REFUNDABLE AS IT IS AN ITEM OF SAFETY EQUIPMENT. The Smith Method replaced the older Smith Maze model but has had some significant upgrades, one of which is the introduction of zonal koroyd. Initially developed for the aerospace sector, Koroyd was originally conceived as an energy absorber. Through exploration, it was discovered that cylindrical structures possess remarkable resilience in nature, displaying exceptional impact absorption capabilities relative to their compact size. Drawing from this remarkable insight, Koroyd® utilizes the power of cylinders to create a groundbreaking framework that exhibits unparalleled behavior compared to conventional protective materials. In contrast to traditional substances that operate akin to springs, storing and releasing energy, Koroyd® functions as a bona fide energy absorber. It effectively converts kinetic energy by collapsing or crumpling upon impact. This distinct characteristic leads to the superior absorption of impact energy, offering enhanced protection and performance. Lightweight in-mold construction fuses the exterior shell and EPS foam for a one-piece design that’s lightweight and durable Zonal Koroyd® coverage for lightweight, energy-absorbing and ventilated impact protection Self-adjusting lifestyle fit system flexes to match your head shape for maximum comfort AirEvac™ ventilation system integrates with Smith goggles for fog-free lenses Removable ear pads for form-fitting comfort Designed for ultimate integration with Smith goggles for maximum comfort and venting Eight fixed vents for consistent airflow Removable Snapfit SL2 ear pads add warmth and are audio-chip compatible Removable goggle strap lock for streamlined shell when goggles are worn under helmet Beanie compatible Aleck™ audio systems compatible CE 1077B Certified (Snowboarding & Skiing)
