Mine both wear Weatherbeeta, not sure what brand, but they cost about 50 pounds on sale at HOY. The 4'6" Orican fits my looooong backed 14hh pony perfectly, I've had it a few years and she's never been rubbed in it. I think 4'6" NZ is 6' British. Tally's also fits him nicely, and it doesn't rub even though it's a bit small (4'9" is way too big though!)
