Rambo SI Hoody Sizing?

[JingleTingle]

Has any one got any idea of how the sizing is on these rugs please? Generous/snug fit etc. My horse is in a 6'6" good quality winter rug but in 6'9" in cheapy SI rugs so not too sure what size to order.

Any input very welcome - thankyou!

All my horses and ponies that have had them have had good chests, so I've found that they have all done better one size up - as typical rambo rugs, you can't adjust them around the chest!
