I found the 'neck hole' on the one I bought was faaar too big. It fitted her length perfectly but the neck was too wide, it was low at the front and slipped behind her withers. I gave it away as 2 hours of wearing it rubbed her raw. And she's a big shouldered cob! Maybe it was just that style but I've never bought one again. Am vaguely tempted by their Ultimate Turnout rug, but don't know whether to risk it!
I haven't used the ones with a neck, but have used the regular stable rugs They aren't bad, but I have good middleweights, and they need a size bigger than usual.
I've had a couple of the really cheap sale stable rugs, under £20 each, & thery have lasted well. They are a little sponge like though when it comes to soaking up wee!
Didn't even think of that Maesfen! Good job it was only a cheapie in the sale, or I'd really be kicking myself now! Lol
(then again, I'm the idiot who managed to sew the tough skin on my hand to a pair of trousers I was altering without realising, so maybe its best I leave needles and thread well alone )
I once bought a Requiste rug & found it to be flimsy & the straps became like string very quickly. Perhaps a one off, I couldn't say as I never bought another.
