Japanese astronaut Koichi Wakata spent two months on the International Space Station (ISS) last year, performing a large number of important scientific experiments, but will probably be best remembered for not having changed his underwear once during the entire mission. As described here, one of his tasks was test driving special “J-Ware” underwear, designed for the Japanese space agency. The underwear, and other clothing, is treated with anti-bacterial and deodorant chemicals, but also effectively wicks moisture away from the skin and dries quickly. Additionally, it is flame-retardant, anti-static, and insulates the body effectively. And now, the company which makes these space-age pants is taking orders for a limited supply of these clothes. You too can wear the same underpants as japanese astronomers! Place your orders here.
