Period-proof underwear: a growing trend in sustainable fashion

People who menstruate have an average of 450 periods over their lifetime, according to the U.S. Association of Reproductive Health Professionals. In the United States alone, 42 million people use tampons regularly, as stated by the 2017 Simmons National Consumer Survey. Considering the average period lasts five days, if Americans use three tampons a day during their periods, they will throw away 283.5 billion tampons in the course of their lifetime.
