2. System Overview Functions: The inside of the [ventilationVest] is made of 3- dimensional pressure-resistant flexible fabric. It is permeable to air and serves as a spacer between skin and clothing. The fan units in the side pockets start at the push of a button. The fans blow air constantly into the 3-D fabric. The airflow causes an even cooling effect all around the body. Damp air is continually exchanged for ambient air thus preventing any moisture inside the vest. The cooling effect is based entirely on evaporation. How it works: The additional evaporative chill effect supports the natural regulation of the body temperature. Please note: This system works best on clammy skin.

3. Special features and advantages [Lighter] Weight At a weight of only 2.87 lbs (1.3 kg) it is truly very comfortable to wear. [More Flexible] Cooling Cooling on demand: The cooling strength can be adjusted according to the user's needs by activating either one or both fan cartridges. The airflow is always evenly distributed even with only one fan running. Maximum air delivered: 400 litres (14.1 ft³) per minute. [Easier] use It's easy to handle, it's easy to clean and it simplifies logistics thereby saving valuable time. Up to 9 hours of operating time. The vest can be worn underneath working and protective clothing. System includes 2 patents!
