18" seat - Wool - tree size on the flap says 31.5 which should be a MW but I put it on several horses and it fits my Medium horse best . Flap is about 17" long. Option to use either a short or long girth!
This saddle was just completely reflocked with new wool and now has nice soft panels again. May need to have wool topped off again after a few rides as the new wool compresses
