This saddle is sadly offered for sale...again... Bought it back from a friend less than a month and a half ago, and while it looked like it fit at first, it is pinching my horse.
The CTD brand is made by Stubben using the same leather and tree as normal stubben saddles, but is considered their off-brand.
17.5 inch tree, medium tree. Beautiful saddle that has been well cared for. I call this saddle my "velcro-saddle" because it really holds you in place well for over fence work and flat work. Deep seat and generous knee and thigh blocks. Will include a girth if I get the asking price.
