Soft, soft polar fleece with polka dots. This is a soft polar so it has a little give. Double polar on top. The same design as our ever popular polar fleece vests with a zipper up the back that gives a great snug fit. Remember, that it is a vest, so it should sit to cover the dog's loins as this keeps the kidney's warm. Great for walking and playing at the park. Machine washable and cool tumble dry.
