A cooling vest made especially for children, the Children's Cool Vest is a durable and comfortable garment that will help safeguard your child against heat stress. The Children's GlacierPacks that are included with the vest are the innovation behind keeping your kids cool and comfortable. Four packs are included in the set: two for the front and two for the back. Use all four packs for maximum cooling. Or use just one on each side to lighten the load. A mesh bag, also included, makes it easy to transport, recharge and store the packs.
