Underwear used to be a pretty simple garment, until people started to pimp them out for the most insane reasons. First, we saw a pair of boxers that were created to conceal your boners. And now, a British company is distributing underwear that protects your junk from radiation.

According to the Daily Mail, London-based physician Joseph Perkins became so concerned about the effects of carrying a cell-phone in his pocket that he decided to invent an underwear line that prevented “dangerous” Wi-Fi signals from fucking up his sperm count. He decided to call the company Wireless Armour.

“Like so many people, my smartphone and laptop use has increased dramatically in recent years, which made me realise that I was exposing myself to large amounts of electromagnetic radiation, mostly centred on my groin,” he told the Daily Mail. “With my physics background I knew there must be a way to shield from electromagnetic radiation using a simple solution.”

That solution turned out to be a pair of cotton underpants that had pure silver woven into them. The metal supposedly protects your Johnson from 99.9 percent of electromagnetic radiation, which is emitted from all sorts of devices, like phones, laptops, and tablets. But that’s not all: The thin threads of silver also make the garments antimicrobial, meaning you’re also protected bacteria and foul smells. What’s not to love?

The Wireless Armour selection offers two styles of underwear: boxer briefs or trunks, which are available in a 180 model for front protection, or a 360 model for full protection.

Take a look at the underwear in the image above. You can learn more about the product, as well as purchase a pair, from Wireless Armour’s online store
