ALPINESTARS YOUTH NECK SUPPORT ALPINESTARS YOUTH NECK SUPPORT ALPINESTARS The Alpinestars Youth Neck Karting Support is designed specifically for young drivers and supports the helmet to help prevent neck compression injuries during an accident. The injected polymer frame has been extensively impact tested to help create an alternative load path for impact energy. If the helmet is in contact with the neck support at the moment of impact, the overall load passing through the neck can be reduced which may prevent a fracture from occurring and reduce the chance of muscular injuries from extreme head movement.Details: Manufacturer: Alpinestars Manufacturer Part Number: 6540118 Sizes: Youth Color: Black/Yellow Compact and easy to use lightweight neck protection fits kids from 8 to 14 yrs.
