The Ruffwear Overcoat Fuse Insulated Vest is an insulated dog vest with an integrated harness, so one layer covers both warmth and the leash connection. An aluminum V-ring on the back and a reinforced webbing loop on the chest offer two clip points, and high-loft recycled polyester insulation adds warmth on cold walks. What Our Gearhead(R) Experts Are Saying:"On cold mornings, I buckle one piece on my dog instead of a coat and a separate harness. The leash clips to the ring on the back, and a few treats ride in the zippered pockets."
