The Cooling Headband keeps you cooler while working out in the gym or when outdoors playing sports or participating in other activities in the heat. Simply wet with water and wring to activate. The specialized air pocket construction quickly absorbs and retains water better than standard materials, and enhances air flow into the damp cloth, creating a prolonged cooling effect. The moisture wicking properties draw moisture away from your skin so you stay dry and comfortable. The Cooling Headband remains dry to the touch. Simply re-wet and wring to reactivate and refresh as necessary. 100% eco-friendly chemical free microfiber polyester construction. Size: 9-7/8" W x 4" H (material may vary in size plus or minus 1/4 and cannot be avoided).
