Kimball Midwest's Cool-Offs are heat-reducing headbands and neck wraps that last up to 72 hours. Cool-Offs are soaked in water for 10 to 15 minutes, or placed in the freezer or refrigerator. The extra-long length Cool-off band can be worn around the neck or secured as a headband, with button hole closure to keep it in place and comfortable. The lightweight Cool-Off has four quilted sections that provide an even distribution of hydration material, and the outer shell is made of 100% cotton. Inside, the cooling crystals absorb and lock in water, reducing the "slimy effect," to provide evaporative cooling and comfort.
