FLAGLINE HARNESS is a lightweight and extremely simple chest back, ultra-lightweight, wear-resistant, non-sticky hair, and puppy wear without restraint. The use of polyester spun ripstop fabric can increase the durability of the product and make the product less likely to be scratched by outdoor stones, weeds, etc. The back has a handle to help the dog lift the dog when crossing rocks and rivers outdoors. The abdomen is designed to help disperse gravity when lifting the dog, allowing the dog to be lifted easily.
