  • Patent number: 5755110
    Abstract: A cooling vest having a plurality of elongated pocket partitions formed on front side and backside vest portions for containing beads of polyacrylamide material that absorb a liquid, such as water, to form a gel that may be chilled, or frozen, to provide a cooling effect on the upper torso of a human wearer. The cooling effect is facilitated by non-impervious properties of a double layer fabric used in construction of the vest that permit evaporation. The front side portions of the vest also provide surface area upon which to add fashion appeal ornate designs, or on which utility pockets are formed. The vest is further provided with a collar member having a partition for containing polymer material. The upper shoulder blade area of the backside of the vest is divided from the lower lumbar area by a stitching pattern that ornate the backside of the vests and that separates the upper and lower polymer containing partitions.
