Smartly appointed for urban and suburban commutes, the Columbia Tech Trekker Insulated Jacket for women offers a lightweight, thermally-efficient design with miles of motocross-inspired styling. If you associate Columbia with backpacking and camping jackets and other outerwear, the Tech Trekker Insulated Jacket will redefine your expectations. Between the outer water-resistant shell and the inner soft taffeta lining are 80 grams of synthetic polyester insulation. Columbia also applied their Omni-Heat (R) thermal reflective lining to help retain body heat close to your core. Omni-Heat (R)thermal reflective linings feature thousands of tiny dots that bounce heat back at your arms and torso, while allowing moisture to escape through the breathable taffeta. Urban refinements in the Women's Tech Trekker Insulated Jacket include an easy-access media pocket and headphone port.
