Bandoogator Cool Tie | Made in USA | Unisex | Water activated cooling bandana scarf This is our most versatile design. It has a tie closure that can be worn tied around the neck or head. We make our cooling band narrow and so it’s just the right size and lightweight, yet effective. We turn and hide all of our seams and finish our tie ends at an attractive angle for a quality look. All Blubandoo cooling headwear contains our exclusive, high performance, non-toxic polymer cooling crystals made for us, to our specifications, for this exact application. Our cooling crystals evolve into a gel when immersed in water. Within minutes your Neckbandoo will completely dry to the touch, yet the active gel will remain hydrated and cool the wearer, due to evaporation, for several days before slowly returning to its original crystal state. No refrigeration is necessary and all of our high quality Blubandoos products are reusable and hand-washable time and again. **Please note: high humidity can affect the cooling effects of evaporative cooling products.
