If you’ve ever seen police officers walking around in full gear during a heat wave, you’ve probably felt a little faint just looking at them. Lucky for them, scientists from the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have devised a new “smart” protective garment that cools down your body instead of keeping it heated up. With a mini-fan and a cooling water system, police officers are way more likely to be able to stay cool under pressure. Click ahead to check out this innovative new garment!
