And you guys thought I was weird for wearing the same pair of hemp pants for a year while washing them once a week. As it turns out, I could have worn them much longer and helped save the human race from utter destruction by never laundering them a single time! (Okay, maybe after getting shat upon by my son a washing would have been appropriate.)
University of Alberta student, Josh Le, wore his pair of raw denim jeans for 15 months before washing them. In a university lab bacteria samples were taken before and after washing as well as after wearing the pants for just a couple of weeks.
