An conditioning system is shown for a helmet having an impact resistant body with an exterior, an interior which defines a head receiving cavity, a front region and having a back region which is located adjacent a lower edge of the helmet body. A first opening is provided in the helmet body located at the back region of the helmet body adjacent a lower edge thereof which acts as an air intake opening. A blower fan communicates with the air intake passage for drawing air into the intake passage and forcing the air from the back region of the helmet in the direction of the front region thereof. A thermoelectric cooling element is located in the helmet interior in communication with the intake passage downstream of the blower fan. The thermoelectric cooling element has a cold side and a hot side. A DC power source is provided for powering the thermoelectric cooling element. An external heat sink is located on the helmet exterior and is connected to the hot side of the thermoelectric cooling element by means of a second opening in the helmet body. Air passing over the thermoelectric cooling element is cooled and air conditions the head receiving region of the helmet.

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.
