The Headmaster Collars are unique, low-profile cervical collar with a tubular design that reduces heat retention.
Easy to fit and adjust; bend the tubular support to adapt for neck flexion or extension.
To size, measure from the center of the chin to the corner of the mandible. If measurement falls between two sizes, order the smaller size.
Small 4" (10cm)
Medium 4-1/2" (11cm)
