Achieving phenomenal warmth in cold and wet weather, this hoodie features ThermoBall, powered by PrimaLoft—TNF’s new synthetic alternative to down. As compressible as down, the clusters of round synthetic ThermoBall trap and retain heat within small air pockets to provide effective insulation, even when wet. Wear or pack this highly compressible, ultralight zip-front layer for reliable thermal insulation in a variety of winter conditions. This midlayer packs into its own pocket and is detailed with bound cuffs and hood, low-profile internal hem drawcord and two interior easy-access pockets.
