Made with polymer cooling technology, 6716 Cooling Hard Hat Liners keep your forehead cool in the heat. Evaporative cooling technology activates when submerged in water. Once fully saturated, wear these cooling pads up to 4 hours. Reactivate the cooling process by soaking them in water again. These liners securely fit most hard hats and safety helmets with the hook-and-loop straps. Just attach the straps to the forehead suspension located in the hat, and you can stay cool while on the job. Comfortable, cotton material does not create bulk under hard hats. These liners are ideal for working outside in jobs like construction. Handwash and air-dry to preserve material longevity.
