Prestige Cool-Coats are activated by water, they are light, cool and soft to the touch, making them luxurious and comfortable for your dog to wear. The Cool-Coat will make your dog feel cool, not wet. You can test this by putting your hand beneath the dog`s coat and feeling how cool he feels compared to any part of his coat that is exposed to the sun or heat for a period of time. As the heat of the day slowly evaporates the moisture from the Cool-Coat, this in turn draws the heat out of the dogs body. Leaving him feeling far cooler than before. When your Cool-Coat coat starts to dry out, it will begin to go back to its natural state, becoming slightly dryer, and a little stiff. When this happens, simply re activate your coat by putting it in water. Immersing the Cool-Coat in water for just a couple of minutes. Once the Cool-Coat is completely saturated, remove the coat and squeeze out the excess water, so your coat feels cool, yet not wet. To clean your Cool-Coat, wash through thoroughly in clean water, if really dirty, it is safe to put your Cool-Coat through the washing machine. Please remember to wash dark colours separately. To store, simply allow your coat to dry and pack away. Our Cool-Coats are made from 100% synthetic material, they are simple to use, wash and store.
