Sock It To Cold Feet

Clothing

America’s astronauts no longer will wear cotton socks when they walk in space. Cotton is too cold and clammy, they say.

After testing more than 30 sock styles and fiber combinations, ILC Dover, the company that makes NASA’s multimillion-dollar space suits, chose DuPont’s ThermaStat as one of the most effective sock fabrics for warmth, lightness and moisture-wicking properties. The fine filaments help block radiant heat loss, a DuPont spokesman said.

NASA will be using over-the-counter Wick Dry and Wick Dry Turbo model socks made by Fox River Mills. , DataTimes
