A flexible head support worn between the chin and the chest to support the head of the wearer and reduce the possibility of neck strain or injury. The head support allows the wearer to freely move their head in all but the forward flexion direction. Adjustable straps are attached to the support in order to secure the support to the wearer. When properly worn, the head support provides a secure rest for the head of the wearer, reducing strain on the neck caused by the weight of the head when performing tasks requiring prolonged neck flexion. A central hole may be provided in the support to reduce the possibility of airway injury during use.
