The first Japanese astronaut to live on the International Space Station is testing a new line of clothes called J-ware by wearing his underwear for a week. Created by textile experts at Japan Women’s University in Tokyo, the underwear is designed to kill bacteria, absorb water, insulate his body, and dry quickly. They’re also flame-resistant, anti-static, and according to an official with the Japanese Aerospace Exploration Agency, comfortable and stylish. If only they could make coffee and walk the dog, too. If he makes it a week without the other astronauts holding him down, stripping him, and spraying him with Lysol, the clothing will be released to the public soon.
