Made with advanced, PVA cooling technology, 6715CT Cooling Hard Hat Pads keep your head cool while working. 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. Pads securely fit most hard hats and safety helmets with the hook-and-loop straps. Just attach the straps to the suspension located in the hat, and you can stay cool while on the job. Comfortable, cotton material does not create bulk under hard hats. Pads are ideal for working outside. Easily machine-wash and air-dry to provide material longevity.
