It's a harness. It's a coat. It's a coat with a harness built right in! Simply slip on, clip in, and go with this rugged workhorse of a jacket that has a water-repellent coating to shed light moisture and a fleece lining for added coziness. The integrated harness means you can leash up confidently at two leash attachment points: one on the back and one at the chest – great for redirecting dogs that pull on-leash. Stash pick-up bags or small essentials in the two zippered pockets, and you've got a coat that's ready to go whenever you and your dog are. The Fuse Overcoat is designed for a "relaxed" fit. In between sizes? Go for the larger one.
