The Ruffwear Climate Changer Fleece Jacket is a dog jacket in quick-drying recycled polyester fleece that holds warmth without adding bulk. A sleeved silhouette and a side zipper hold heat around the core. Articulated sleeves keep the front legs moving, and an active, tailored fit hugs the dog's body. What Our Gearhead(R) Experts Are Saying:"I buckle my pup's harness first and pull the jacket on over it. The leash clips through the soft portal on the chest, so the harness stays where it was fitted and the fleece stays on for the whole hike."
