The Storm Mask Enshroud is a dual-purpose riding accessory, protecting your face, neck and head from the cold while enhancing protection when worn under a helmet. The dynamic feature of the Storm Mask Enshroud is a double-layer fabric in the upper section with superb friction-free slide-ability. If you suffer a lateral impact the movement of the upper facemask helps the helmet to absorb a significant amount of rotational energy before it is transferred to the brain. This benefit is scientifically proven in laboratory tests! Now with integrated pocket for the use of interchangeable filters (filters are not included).
