Made in Australia, this innovative cooling system will help keep your body temperature in check in hot climates. Made with non-toxic crystals, you soak your Cobber® in cold water for about 30 minutes. The crystals expand to a gel and will stay that way for three days. Once back to its original form, soak it again. Place it around your neck, the Cobber® will cool the cartoid arteries in the neck, keeping you cool and comfortable. The fabric is a poly/cotton blend. Available in multiple patterns, suitable for men and women.
