I've just received the lightweight Supreme I ordered last week... I am SO sad that it's too big and I'll have to wait even longer for the next size down to arrive! It's lovely, fits perfectly round my horse' front and is nice and deep round her belly. Well worth the money (and I hope it will last for years too!)
I love mine, I bought a MW rug and got a spare HW neck as the MW neck has no fill. (I was going to get the Rambo Plus but apparently even the combo necks on MW rugs have no fill). My horse has been warm and dry ever since. This is the first Horseware rug I've bought that has the leg arches - all my others are quite old (pre arches) and I think they are a fab invention.
My guy has the mw supreme which I managed to pick up as a bargain from ebay. he also has the premier equine stable rug and I have to say the cut on the premier equine is very very similar to the rambo. So if you are concerned about the penies then I would suggest looking at premier equine.
I have heard very good reviews from people on here about premier equine but as I don't actually hqve the turnout can't comment on like for like comparison
