Sizing comes up REALLY BIG on those ones, as tbh the one i've got is too big for horsey but much better than the masta one of the same spec/price which slid all over the place.
Jasper Extra Lite without neck, but sizing came up a bit small - it's the only 6'3" my boy has that isn't on the tightest holes. Gorgeous rug though, fits lovely and always looks smart. Can't recommend it highly enough!
Another vote for Jasper rug here, but I found it came up small as well. I got it in a set with NZ and fleece, and they still fit fine, but the jasper is no longer usable. I wish they did them with 2 front straps though, as I find the single one digs in.
I've got an Amigo one, its really good and fits well, its very light & i've used it as an under rug alot as well, I've had jaspers as well and TBH they are also good rugs, i think they're much of a muchness but when i bought the amigo it was cheaper than the jasper, so that swayed me!
