Yes. The American Society for Testing has established a standard test procedure (ASTM D7024) to measure the effects of changing temperature and a fabric's ability to absorb, store and release energy.

Founded in 1898, ASTM International is one of the largest standards development organizations in the world.

"Patented technology was originally developed for use in space gloves to protect against extreme temperature fluctuations & is a shining example of how mankind benefits from the space exploration, often and unexpected ways."
