Thinsulate (Wikipedia)

Thinsulate is a brand of synthetic fiber thermal insulation used in clothing. The word is a portmanteau of the words thin and insulate, trademarked by 3M. The material is made by the 3M Corporation and was first sold in 1979. It was originally marketed as an inexpensive alternative to down; at the time, 3M claimed it was twice as warm as an equivalent amount of any natural material.

Originally designed for clothing, it later became popular as an acoustic damping material. In 1997, 3M generated US$150 million in annual revenue from the product. Its development originated from other microfibre products made by 3M. It has been used in US army clothing since the mid 1980s.
