All net windows are made of solid material and will not be scratched by claws. The top and left side curtains can be rolled up and secured with a special elastic band. When not needed, the pet can be seen in the bag only through the net window. The side net window can be easily opened by a zipper, and a special strap is used to fix the net window. The dog can poke out the head. The other side of the bag is a pocket for other objects, and there are rubber bands to secure the kettle. Even if the dog is so small that he can freely enter and exit from the side net window, he can only poke his head out of the bag because of the built-in dog band.
