Whether it's a patio misting system, a commercial fog system, fog effect or water feature, Aero Mist misting systems and fog systems are a do-it-yourselfer's dream come true.

How does it work? Cool Vest is made with a special fabric that absorbs and retains water. It uses no toxic chemicals, or materials. The vest utilizes a simple scientific principle - cooling through evaporation! As water gradually evaporates, it takes the heat around it. The same effect happens when you soak a T-shirt in water and wear it to cool down on a hot day at the beach. From experience you know how effective this is in cooling you down. The differences between using a wet T-shirt and this product are 1: the liner is laminated so dogs don't get wet and, 2: this special fabric doesn't dry out as quickly as a cotton T- shirt would. The result is you don't have to deal with a messy, wet dog while trying to make them comfortable and you don't have to run for water every 15 minutes to... Less
