Very nice harness

I have 3 parrots and they need to go outside. It is really good for them. However for their safety they need to be on a harness when they go out. This way they cannot fly away and get hurt or disappear. The harness is made of a smooth nylon that is not too heavy for my green cheek conure and cockatiel. I did have a hard time getting the fit right on my birbs and it did slip some (reason for only 4 stars). One thing that would have been nice was some insructions on how to adjust and still keep the chest part centered.
