North 49 Neck and Head Wrap

The Heat Guard Cooling Tie is a tubular tie containing polymer crystals. The crystals absorb water, expanding to more than 400 times their original weight. This water is slowly released onto the fabric, keeping it cool through the natural process of evaporation. No refrigeration is necessary. The great absorption rate of the crystals allows for sufficient water storage to produce a continuous cooling effect for 1 full day.
