Abstract
Abstract A cooling apparatus (10) includes a first sheet (12) and a second sheet (14) both formed from chamois. The sheets are sewn together along a circular line (28) to define an enclosure adapted to receive a quantity of ice (30). The enclosure is provided with an access port (16) which is normally closed either by means of a zipper (20) or by means of a VELCRO closure. In use, the cooling apparatus (10) is placed on the head (32) of a user and is concealed and retained by a cap (34).
