There is no credible evidence to verify whether Kitex Garments collaborated with Jockey to create clothing using NASA technology.
NASA stated in 2012 that NASA began looking for a novel technique to keep astronauts comfortable more than two decades earlier; however, they developed this technology for gloves and not underwear. Temperatures on a spacewalk might range from 250 to -250 degrees Fahrenheit. Phase change material was one of the technologies NASA looked into to assist in maintaining the perfect temperature.
Furthermore, NASA reported that Mo Moorman, the director of public relations at Jockey International, stated that by March 2011, Jockey had released a full line of men's and women's Jockey Staycool underwear - incorporating NASA Spinoff technology - to manage temperature and sweating.
However, neither Kitex nor Jockey have issued an official statement on collaborating to create any temperature-controlled underwear using NASA technology.
