The Cobber

This unique neck wrap is filled with organic, non-toxic polymer crystals that have a cooling effect when immersed in water. Because the crystals absorb 400 times their weight in water, the Cobber stays cool for several days (even after the outer fabric has dried), and can actually lower body temperature by 3-4 degrees. Also helps relieve headaches and fevers. (91cm long; 28g dry)
