This serious jacket retains body heat and is one of the softest, lightest jackets Columbia has ever made. Made to keep you warm without weighing you down, it features responsibly-sourced 590 TurboDown™ Insulation for a featherweight feel, Omni-Heat™ thermal reflective technology which is made with a pattern of metallic dots to reflect and retain the wearer's body heat, creating warmth without adding bulk, and water-resistant fabric for protection from the elements.
