Medium-sized dog jacket made of nylon and fleece, with a button closure design for comfort. A 3-way cold weather garment. Purchased at Petco in Hawaii, but it was too small for my dog, so I'm selling it. I only wore the nylon vest once to take pictures. It's super cute! Please check the images with the measuring tape for the size. - Brand: Arcadia Trail - Color: Blue/Gray - Material: Nylon/Fleece - Size: For medium-sized dogs - Design: Button closure, Velcro closure Thank you for looking.
