Warm up cool days with this cozy, sherpa stylish wrap vest jacket by FuzzYard. The Fitzroy Jacket is not only warm and lightweight, but it also features a dual multi-function zipper on the back. Either unzip from the top to open up the neckline or use it as a harness hole. To secure the vest, pop your dog’s head through the head hole and connect both velcro patches on the underside. The velcro allows a little room for adjustment, so you can tighten or loosen it according to your pup’s size or fur thickness.Available in 7 sizes: Size 1: 38-39cm (chest), 26-29cm (length), 24-26cm (neck) Size 2: 44-45 (chest), 30-33cm (length), 28-30cm (neck) Size 3: 51-52cm (chest), 35-38.5cm (length), 33-35cm (neck) Size 4: 59-60cm (chest), 40-41cm (length), 37-39cm (neck) Size 5: 66-67cm (chest), 45-46.4cm (length), 42-44cm (neck) Size 6: 76-77cm (chest), 59-62cm (length), 45-47cm (neck) Size 7: 86-87cm (chest), 69-72cm (length), 50-52cm (neck)
