Collars that pop! The club collection by lupine is inspired by the distinctive look and feel of the classic polo shirt. In six rich color combinations. Made From recycled plastic bottles (pet). The upper layer is a soft woven material with a luxurious silky feel, embellished with the lupine logo. The base is a super-soft woven material that matches the logo’s color. To protect your pet’s fur and skin, all the ends of the material are turned under and stitched. Made with a welded steel d-ring and custom side-release buckle. Lupine products are not recommended for tie-out.
