The North Face ThermoBall Full-Zip Jacket is designed to provide phenomenal warmth in cold and wet conditions. Developed in partnership with PrimaLoft, ThermoBall insulation technology utilizes small, round synthetic-fiber clusters - which closely mimic down clusters - to trap heat within small air pockets to retain warmth. ThermoBall insulation is just as compressible as down and insulates even when wet! Lightweight 100% nylon fabric construction combines with a mock-neck collar, full-front zipper, elastic-bound cuffs, and a slight drop-tail hem to seal in body heat for even greater warmth. A hem cinch cord in the hand pockets allows easy adjustability for a personalized fit. The three-color zipper pull detail adds a touch of style. Two zip-secure hand pockets provide convenient storage for your essentials. The ThermoBall Jacket stows in its own hand pocket for easy transport. Imported.
