we've recently upgraded the design + materials on one of our most popular products! not only will your thrill sniffer will enjoy more room to snuggle up, but they'll also appreciate the new waterproof base. the base and trim are black, the center is our bright green and the interior is grey. the top can be unzipped almost entirely so you can help your pet in/out of the bag or lay it flat for use as a pad or blanket.
