• Before ordering our dog coat, measure your pet's chest and neck circumference. If any measurement is between two sizes, choose the larger size. • High-quality materials: outer layer of waterproof material and breathable polyester, with a warm cotton-lined inner layer to maintain the dog's body temperature. • Easy to use: adjustable velcro closure and double row of buckles on the back for a perfect fit. • Wind-resistant: retractable cord at the neck and adjustable cuffs to prevent wind and keep warmth. • Easy to control: durable D-rings on the back to connect the leash and high-brightness reflective strips for safe walks even at night.
