The invention provides a protective collar for use with a full-face crash helmet, particularly for use in motor sports. The collar is at least partially formed from a resilient material that in use extends peripherally entirely around a user's neck. The collar has a recess in which a lower part of the crash helmets is received and secured, and helmet retaining means (e.g loop-pile fastening strips) are provided for retaining the helmet within the recess. The recess has an upwardly facing bottom surface which abuts the lower part of the helmet and a peripherally extending, inwardly facing wall surface which extends upwardly from the bottom surface. The wall surface closely fits against the lower part of the helmet around the periphery of the helmet. The collar is shaped to limit movement, both laterally and in a fore-and-aft direction, of the wearer's head in the event of a violent acceleration or deceleration, such as may occur in an accident.
