Have you ever had the notion to want to wear your underwear more than one day at a time? If so, Japanâ€™s space scientists may have just the thing to enlighten your fanny: a line of odor-free underwear and casual clothing. The clothes are designed to kill bacteria, absorb water, insulate the body and dry quickly. They are also flame-resistant and anti-static, and for the fashionistaâ€™s they are comfortable and stylish. They have plans to make the clothes available to NASA when the development is complete.
