A mat for cooling a person on the beach, side of a swimming pool, and even in a vehicle, is provided with recirculated ice water from an insulated reservoir using a small battery powered pump. The mat is made of sheets of urethane coated nylon or PVC film that is heat sealed on all sides, and to tubes that contain the ice water in and out. The sheets are also sealed to provide channels that hold extruded strips so formed as to assure that ice water will continue to flow through the channels even when the weight of the person would tend to close the space between the sheets.

A mat for cooling a person lying or sitting on the mat comprising two sheets sealed together to form a cooling bladder, a reservoir containing ice water to be recirculated through said cooling bladder, two tubes connected to said bladder for conveying said ice water from said reservoir and back to said reservoir, one tube being connected at one end of the bladder and the other of said two tubes being connected at the opposite end of said cooling bladder, said two sheets being further sealed together to form parallel channels that are spaced from sealed sides of said cooling bladder and spaced from sealed ends of said cooling bladder thereby to provide flow of said ice water from said one end to said end of said cooling bladder, and extruded strips inserted in said parallel channels to prevent the two sheets from collapsing against each other due to pressure exerted by said person, said strips being extruded with a cross section which will assure a passage of said ice water through said parallel channels even while said person is lying or sitting on said mat, and further including an air bladder connected to one surface of said cooling bladder for insulation of said cooling bladder on said one surface while said person is lying or sitting on said mat.
