Innovative technology for unconditional thermal efficiency - The Women‘s Thermoball Hoodie by The North Face. The synthetic jacket comes with ThermoBall technology, developed by The North Face and PrimaLoft. It combines the best properties of synthetic insulation and down insulation: excellent thermal efficiency, minimal bulk and weight and insensitivity to moisture.
The whole thing works by imitating the structure of down with tiny, compressible synthetic fiber balls. The tiny balls have the compressibility, weight and thermal efficiency of down with 600 cubic inches of fill power, while still retaining their insulating properties when wet!
The ThermoBall insulation is protected by a tough, lightweight outer material made of ripstop polyester. An adjustable hood, multimedia-compatible pockets, elastic cuffs and a drawstring hem complete the package that is the light and warm Women‘s Thermoball Hoodie by The North Face.
