The Leatt-Brace^(R) is an injection produced glass reinforced nylon or carbon fiber and Kevlar neck brace system designed by medical professionals and motorcycle enthusiasts to help prevent:

• Hyperflexion: extreme forward head movement
  
• Hyperextension: extreme rearward head movement
• Lateral Hyperflexion: extreme sideways head movement
• Axial loading: compression of the spinal column due to the effect of force on the helmet
• Posterior hypertranslation: rearward movement of the head/helmet on the neck.
