The Deluxe Sport is designed for the every day user in mind. With this vest comes added styling that not only keeps you cool on those hot days, but also looking cool at the same time. The light weight and low profile fabric technology is the most comfortable option whether you work outside, exercise outdoors, compete as an athlete or simply use our products to make your life more enjoyable. The ideal environment to gain the most from evaporation technology is in dry, sunny, breezy places. The more exposure to the elements that help evaporation the cooler the vest will become. A fan is a great way to help make the vest cooler faster. The duration between soaks vary depending upon how long you allow vest to soak, and the amount of water retained after wringing out the vest.
