The AlphaCool Cooling Fan Jacket has 2 high-powered fans that circulate air directly around your body for cooling relief. The AlphaCool Cooling AirJacket is one-of-a-kind and works great for keeping you cool in the summer heat, inside or outside. There are two powerful fans (on either side near the back) built into the jacket. The breeze created by the fans creates a strong cooling sensation. This cooling jacket is perfect for long, hot summer days at the beach, gardening, at a ballpark, or working in hot conditions. Staying cool and regulating body temperature is important to stay safe and avoid heat stress. The battery-powered cooling jacket, or "Air-Conditioned Jacket" actively cools down the wearer and lasts for up to 10 hours.
