Ice Cooling Vest

This vest is made of special PVA fabric, which has strong water absorption and water retention. After soaking in water, the water is locked in this vest. Then wear it on the body, so that it can absorb the body heat, convert it into hot air, let the body temperature drop, and the body will feel cool. After fully draining the water, it will slowly become hard, which prevents the invasion of bacteria such as mildew. When using it again, you can also soak it in water. Recycle like this!
