Tie it around your neck and it will cool you down by cooling the blood flow to your head. Leaving it on will keep your neck moist and evaporation will continue to cool you all day long.
Because the water is absorbed into the crystals, the bandana won't drip, but will release water only as the surface starts to dry. This keeps it at an optimal moisture level. It needs to be rehydrated only every few days.
Great for use in the garden. Measures 35" long. Made in USA.
