The North Face ThermoBall Full Zip Jacket

The North Face ThermoBall™ Full Zip Jacket is an ultra-lightweight, synthetic-insulated jacket for outdoor athletes performing in cold and damp conditions. Highly compressible and perfect as a winter mid-layer, this garment features ThermoBall™ insulation - a new development in insulation technology that uses small round clusters to mimic the heat-trapping properties of down. Constructed from a durable nylon exterior and treated with a DWR (durable water repellent) finish for added water resistance, this insulated jacket has a true sweater-like fit that packs super small, making it ideal for backcountry travel.
