This is a gently used Columbia women’s Techy Hybrid jacket. It is called that because of the hybrid stretch and front and back panels that insulate your core to keep you warm where you need it most. Perfect for travel, hiking and other outdoor activities. The shell is 100% polyester and the insulation is Thermarator 100% polyester. It has zippered hand pockets. Please see the photos for ACTUAL tape measurements so you can ensure the perfect fit for YOU! I feel it runs a bit small for a Large personally.
