The North Face ThermoBall Eco liner jacket in a versatile dark gray. Designed as a component for a 3-in-1 jacket system, this lightweight piece features signature quilted insulation at the body to provide warmth without bulk. The sleeves and upper yoke offer a smooth finish, while the full-zip front and stand collar provide extra protection against the elements. Finished with a tonal logo at the chest and snap-attachment points at the cuffs, it functions perfectly as a standalone light layer or a thermal mid-layer.
