Made from reinforced polyamide, the rigid, non-flexible structure of the Leatt Neck Support 5.5 offers revolutionary protection and has been improved over the years to be very comfortable. Leatt neck braces are tested and proven to help reduce neck forces and therefore the risk of serious neck injury by up to 47%. The chassis is designed to fit all riders comfortably. It is fully adjustable, while the structure remains very rigid in the event of a fall. It has a special cut-out for the collarbone, which ensures that the helmet and support do not touch the most sensitive bones in a fall.
