Thermotie

Stay cool in the heat with the thermotie bandana. The bandana is filled with unique polymer crystals. The bandana is soaked briefly in cool water for about 20-30 minutes. The crystals absorb the water and retain it in a gel form. The tie is then placed around your neck and tied loosely. The evaporation of water from the crystals keeps you cool for 8-10 hours and longer.
