If you’re someone who likes to wear the same underwear day after day, then here is the news you’ve been waiting for. A Minnesota company has created “self-cleaning underwear” that — supposedly — can be worn for days, weeks, or even months without changing.

The underwear is made with a blend of bamboo, eucalyptus, beechwood, and copper fibers that destroys all smell-causing bacteria and stays clean. The manufacturer only suggests that you let the underwear air out for a few hours before putting it on again. The creator says he got the idea after he traveled to Iceland and didn’t pack enough underwear.
