100% Nylon Thinsulate fibre filled.
Thinsulate™ is a thin insulating material made with fibers about 15 micrometers in diameter. It is a hybrid word coined by combining "thin" and "insulate" and was first introduced by the company 3M in 1960. Thinsulate™ is lighter and thinner than polyester fibers but provides greater warmth and insulation.
