Do Weatherbeeta Thermocell rugs come up big?

IME they certainly don't come up small!!!!!!! My beastie has one the same size as he normally takes and it is a bit roomy, but probably not a whole size (if you get what I mean!) So I would go for your horse's normal size, then you can layer rugs underneath in winter, and I would rather have a slightly roomy rug, rather than a tight one!!!!!
 
They shrink when you get them cleaned. I had my 6'3" cleaned by a professional cleaner and it only just seems to be about 6' now, if not smaller....
