When most of us realize that we’re overdressed for the weather, we can simply take off that extra jacket or whatnot that’s causing us to overheat. Police officers, however, don’t have the option of taking off their bulletproof vests ... and those vests aren’t exactly known for being lightweight and breathable. Fortunately, a team from Swiss research institution Empa has developed just the thing for those hot cops – an air-conditioned ballistic vest.
