Relief for sultry rides in hot weather. This neckwear is made using 100% cotton fabric on the outside, while the interior is filled with water-absorbing polymer crystals which can hold 350–400 times their weight in water. Because these release water slowly (over a period of days), they cool for a longer time. Hence, increased comfort in hot weather. Completely non-toxic and reusable thousands of times, the Cool Off Tie is a simple, effective tool for heat management, and may help keep you alert and less distracted. 35.5"×1.75. Assorted patterns and colors.
