It’s usually a gift for those who never ever wanted to change clothes, but it has been restricted for astronauts. This is one of the innovations of the Japan Aerospace Exploration Agency where they literally threaded their clothes with anti-bacterial and deodorizing materials. There might be a problem in a closed environment like the space station, where you never open a window for fresh air. With three people confined to the same space, it's generally a smart idea to maintain good grooming habits. The clothes developed were tested by JAXA astronauts during two previous shuttle missions and won rave reviews. In addition to odor control, the clothes are designed to absorb water, insulate the body and dry quickly. They also are flame-resistant and anti-static as well as comfortable and attractive. Because it is expensive to fly cargo to the station and without enough water to wash clothes, astronauts typically discard their garments worn during exercise after three days. So, it’s now time for astronauts where they typically enjoy sweat free clothing and feel fresh air in the space station even after three days. And it is becoming a 100$ billion project in many of the major nations already. These clothes are now have been available only for JAXA’s astronauts.
