The invention is a thin textile garment worn between the head and the motorcycle helmet. The garment forms an independent secondary liner between the helmet and the rider's head and looks in appearance like a balaclava. The garment is made of a material which has a central layer of water absorbent material with the inner surface in contact with the wearer's head being hydrophobic so that it is dry to the touch and the outer surface in contact with the air stream being hydrophilic to allow evaporative cooling from the water retention layer. The absorbency and thickness of the water retention layer may be selected to provide a predetermined period for cooling preferably an hour's cooling or more depending on conditions. The water absorbent liner is composed of microfibres. |
