My 4 year old gelding fits perfectly. It is 15.5 hands tall and 62 inches long. He also looks very cute in it. Lightweight but still warm, love the adjustable back leg straps, unlike his other coat which didn't have adjustable back leg hooks. I had to alter and sew his last coat to make it fit. It came quickly and is super cute! It's mainly blue and red, but there's some pink and orange as well. I chose this one because horses can see blues and reds.
