Chilean company Monarch has developed new underwear that's made out of copper. And if that sounds uncomfortable, don't worry! It's totally not. Turns out copper can kill 99% of the bacteria and fungi that "naturally" develops down there.
It's the sterilizing effect of copper that works the cleansing magic. The copper underwear is made by merging copper with polyamide to produce an oil that's turned into wire. The wire is then woven inside your tightie whities so that the copper stays in contact with your skin so it can kill fungus and resist odor. So fresh and so clean! Of course, even if you do own copper boxers (or panties), please still wash them. It's not an excuse not to. [Guanabee via Geekologie]
