Perfect size for my 350-400 pound girl. Helps pretect her from blanket rubs on her high withers.

Sizing indicates 500-800 lbs pony. My pony tapes at 600 so I chose the small. It works but is a little on the snug size. I expect it will stretch eventually but it rests on the lower part of his mane right now and I am concerned it may rub. Quality is good- strong material, good stitching, and strong Velcro.

I purchased this product last year and absolutely love it. One of his pasture buddies decided to have some fun and not only did his blanket get torn off but so did his Sleezy. It had a slight rip in it, but was still usable. I decided to purchase an extra one just to be on the safe side since he will be body clipped this week. I also have several of their other products that I use during show season - full body, etc. I highly recommend.

I just put this on my large pony tonight since he was just body clipped and it is going to be 23 and require his heavy turn out blanket. The fit was perfect. Has nice adjustment near the withers. Perfect fit, easily adjusted.
