Hmm, I would say they are true to size, but nice and deep. I have a few horses in them and they wear the same size as they did in Amigo rugs. Definitely more generous around the chest, different cut to Weatherbeeta. Love the necks.
My horse who suited a Weatherbeeta didn't suit them at all.
They came up bigger in some areas, far too deep and nearly reached his knees but too tight round the shoulders. Also found the Amigo rugs came up small and too tight round the shoulders for this horse.
I bought a 6'6" for my mare who usually wears Rambo. I had heard brilliant reviews and liked the neck design so decided to give it a go. 3 days and it had rubbed her shoulders :-(
