Thanks to Frank in the forum for this link - odor-free Japanese space clothes (headlined ‘Koichi Wakata can ‘wear his trunks (underwear) more than a week’):
Wakata’s clothes include long- and short-sleeved shirts, pants, shorts and underwear. There are socks too, which in addition to being laced with odor-fighting polymers, are constructed so that there is a pouch for the big toes, similar to how a mitten fits a thumb. The design enables astronauts to use their feet like an extra pair of hands.
Taya is working with clothing manufacturers Toray Industries and Goldwin Inc. on a commercial line that integrates a nano-thick chemical layer into the materials.
“Many of the properties required for clothing worn by astronauts on board a spacecraft can be applied to ordinary clothes,” Taya said in a statement. - MSNBC/DISCOVERY
One wonders how much different this fabric is from commonly available ant-microbial materials (like VisaEndurance) which uses silver-impregnated fibers. A link in the story provides part of the answer: not much. This fabric has fibers encased in silver nanoparticles which may apparently be something of an ecological hazard. Of course my Stinkfighter laundry formula is definitely cheaper and maybe a little greener. Cocona may be greener still. I have some Cocona khakis which are a mainstay in my travel wardrobe, but they’re hard to find.
