Snowboard/ski helmet Smith Maze Mips * certification: ASTM F 2040, CE EN 1077:2007 CLASS B * MIPS (Multi-Directional Impact Protection System) technology: in the event of an impact at an angle, the EPS shell of the helmet rotates a few millimeters after the MIPS layer, and thus protects the head and brain from a violent rotational jerk. Although this movement is only on the order of a few millimeters, the result is that MIPS significantly reduces the amount of rotational force that might otherwise be transmitted to the brain * lightweight in-mold construction combines the outer shell and EPS foam into a one-piece design that is lightweight and durable * designed for maximum integration with Smith goggles for maximum comfort and ventilation * AirEvac™ ventilation system integrates with Smith goggles for fog-free lenses * self-adjusting lifestyle system adapts to head shape for maximum comfort * 9 fixed vents for consistent airflow * removable Snapfit SL2 earcups provide warmth and are compatible with the audio chip * clip on the back for attaching glasses * compatible with Aleck™ audio systems * sizes: S (51-55cm), M (55-59cm), L (59-63cm) * branded helmet Smith * SNB Helmet, Smith Ski Helmet * Smith Snowboard Helmet * Smith Ski Helmet * Smith Helmet
