In beautiful condition, this is the women's Arc'teryx "Narin" Vest. Filled with down, this is a quilted puffer with a hood and side pockets. The shell is made of 100% Nylon and the Contrast is 100% polyester. The insulation is made of grey goose down. This comes in a beautiful blue and is a women's size Medium. I've included the manufacturer's description down below as well: The Narin is a down vest with minimalist design, clean lines and a relaxed urban aesthetic. Warm 750 fill power goose down in the body and Coreloft synthetic insulation in the shoulders provide lightweight insulation with minimal bulk. A simple low profile hood adds protection from unexpected cold. Materials, construction and disciplined design give the Narin a minimalist appeal without sacrificing performance. The Bast nylon face fabric is a light, durable matte taffeta that resists wind and has a soft, silky feel. A durable water repellant finish is added for moisture protection. Refined quilting and fleece panels on the sides streamline the look and fit. Light elastic around the hood and armholes smooth the Narin s lines and seal out drafts.
