The Cordova-brand Cold Snap™ Cooling Towels are comprised of super-absorbent PVA fabric that accelerates the cooling process. Simply soak with water, wring out excess, and snap & shake to activate the cooling process. Cold Snap™ Cooling Towels stay cold for hours. They relieve heat stress through an evaporation process. When the towel begins to dry, simply wet and reuse. When finished, store the towel in the Cold Snap™ storage tube for future use. View our entire Cold Snap cooling line.
