This is a small pony or miniature horse bitless bridle.   The nose lets out to 17” and the headstall lets out to 30”. It is adjustable on the nose and the headstall.  This one is a side pull "with a whoa" which means the noseband tightens when the reins are pulled back.  You can keep it from tightening by attaching the reins to both rings on the noseband. 

The side pull hackamore attachment can be taken off and you can add a bit to this bridle.

This is a set with a bitless bridle and matching reins.  

This bridle is black and electric blue and is hand braided from nylon 550 Paracord.
