Japanese space underwear set to invade Earth?

For some reason, every time high-tech underwear news hits the Internet, my editors think it's something I need to cover (pun intended). This time, though, it's underwear from space. And it's Japanese underwear from space that lasts up to a week before you have to change it--for better or worse.

According to Reuters, the clothing called J-ware is currently being tested aboard the International Space Station, perhaps to the dismay of Koichi Wakata's fellow astronauts.

The skivvies, developed by textile specialists at Japan Women's University in Tokyo, are meant to absorb moisture, kill bacteria, and generally be comfortable in situations where there are no laundry facilities and you really can't be as freshly dressed as you'd like.

Thankfully, so far the tests have been successful. Wakata has been quoted as saying, "Nobody has complained, so I think it's so far, so good." The question is, if the tests are fully successful, will the general, non-space-going world buy into the idea? There are plans for Earth-bound mass marketing of the week-long underwear. I for one am not into the idea, even if it works fine.
