Okay, guys, I couldn't find a size 87 anywhere but found it here. This blanket is great. I just fold up the bottom front corner when riding so I have some leg on. My fair weather attitude mare has responded well by *just* going into a trot, instead of sassing/ear pin/back hop her way into it like a grumpy goose. Love this brand, use it on my horses and on me. Happy riding!
