Carhartt Men's Rain Defender® Insulated Vest - Relaxed Fit, Size L, Black. Gently worn. When it's cool enough to start layering, this men's insulated vest has you covered with a lightweight and insulated design. The durable Cordura® fabric shell is lined with smooth nylon making it easy to throw on over a long-sleeve tee or hoodie or to wear under a shell or heavier coat. Durable water repellent makes water bead up and roll off to help keep you drier in light rain. Previously known as the Gilliam Vest.
