ThermoBall Insulated Jacket by The North Face
The ThermoBall Insulated Jacket by The North Face provides warmth without the bulk of a traditional "puffy" jacket. The square-baffled jacket is filled with polyester using ThermoBall technology, which spins small clusters of the fiber creating similar insulation to down fill. The best part of this technology is that unlike down feathers, this synthetic fill will retain 80% of its insulation capabilities even when dampened by the elements or your own sweat. The jacket has a standard fit and is available in several colors.
