RC Pets West Coast Rain Wear is a lightweight coat that is tailored for a comfortable fit. Keep your dog dry and warm with the water resistant treated nylon shell and cozy fleece liner. Large reflective strips on the sides give you maximum night time visibility. Sizes 6-20 have chest panel coverage, while sizes 22-30 have no chest panel for easy fitting, all with Velcro closures. Machine washable. To correctly measure your dog, use a soft tailor's tape while the dog is standing. Girth equals the widest circumference around the dog's chest. Length is measured from the collar to the base of tail. For dogs that fall in between sizes, choose the larger size for more coverage.
