Wearable cooling/heating system
An apparatus comprises first and second fabric layers having corresponding and aligned elongated rectangular sections, which are stitched together at one or more periphery seams. A water-permeable compartment is located between the first and second elongated rectangular sections at the respective middle portions the first and second fabric layers. The water-permeable compartment has an elongated rectangular topside section and an elongated rectangular underside section, each having a length that is less than the length of the elongated rectangular sections of the first and second fabric layers. The second fabric layer and water-permeable compartment collectively define an opening at the middle portion of the second fabric layer, wherein the opening is configured to receive a cooling medium or a heating medium. The apparatus provides the option of whether to wet the middle portion of the second fabric layer that is in contact with the neck of a user.
