The Marmot Women's Sol Vest is a lightweight vest for warmth and light weather protection at the torso. The Sol has been stuffed throughout with 600-fill down with Down Defender technology. Down Defender allows the down to resist moisture, allowing it to continue to insulate, even when wet. The shell fabric is a 100% polyester mini ripstop that protects the down inside of it, with a durable water repellent finish to prevent moisture from soaking into the fabric surface. Wear the vest alone over your favorite long sleeve, be it a base layer or button up flannel, or layer up under and over for colder adventures. The low profile vest won't be too bulky and still packs a heated punch. Zippered hand pockets and an internal pocket ensure valuables are always within hands reach.
