Down-Like Thermal Insulation Fibers

FENC® uses bionics to imitate the structure of down and designs a 3D spiral hollow fiber with an elasticity that forms an air insulation layer. It comes with better elasticity, higher fill power, better warmth retention ability, and compressibility than ordinary synthetic fiber. It is also lightweight and soft.
