I bought this at Cainz a few years ago. I only used it once for a short time. There was one loose thread. Since a dog wore it, please refrain from purchasing if you are concerned about minor imperfections. It's easy to put on because it fastens with Velcro on the back. It has a reindeer pattern, so it's perfect for Christmas. It seems warm because it's made of knit material. ●Size MD
