Water rolls right off the waxed-cotton surface, while a fleece interior staves off the chill on brisk days. Our waxed-cotton dog jacket goes on fast and adjusts for a snug fit with a hook-and-loop belly band. In green. Measurement reflects neck-to-tail length. To determine the correct size, measure from the base of the neck to the base of the tail. Spot clean with cold water, no soap.
