Japanese spaceman Koichi Wakata on the international space station reported that his specially designed space clothing, dubbed "J-ware," worked as advertised. The odour-free clothes are designed to kill bacteria, absorb water and dry quickly. "In two months, I was wearing these underwear and there was no smell and nobody complained," said Wakata
