I had trouble with the sizing on this bridle. The cob seemed too small, and the horse seemed too big. I ended up going with the cob, and after cleaning and oiling the bridle a couple times, the leather has stretched a little to fit perfectly. I receive so many compliments on this bridle and my horse seems to like it as well. I did use pure neatsfoot oil to darken the leather a little because I prefer darker tack.
