One of the true beauties of the Ghost saddle is the endless possibilities for fit!
The Ghost base is flexible where needed, but semi-rigid in the right places to keep a narrow twist for the rider, distribute weight where the horse is able to carry weight, and provide a structured pommel lifted over the horse’s withers. Ghost does a great job of fitting even the widest horses, including draft breeds. The standard pommel has some rigidity, but it can shape to the wider horse.
These saddles have been tested to maintain spinal clearance with riders at 200lbs–heavier than what most treeless manufacturers suggest–and accommodates both narrow and wide horses. If, for some reason, you have a horse who is narrower or higher-withered than the standard Ghost adjusts for, it is possible to order a more rigid pommel.
The Ghost is flexible to accommodate both you as a rider and your horse’s back, but not so much that it is sloppy. Although the seat is bendable, the point at which it can bend begins behind your seat bones. This allows the seat to mold around you, but not let your seat bones put direct pressure toward the horse’s back.
The stirrups and girth attachments are two elements in which the Ghost is set apart from many other treeless options. While in many saddles the stirrups and girth hang off of a strap which crosses over the spine, on the Ghost, they attach to the sides independently–providing freedom and pressure relief over the spine.
The velcro panels open and a multitude of materials can be used to customize weight distribution, shimming, and other options. Or, for the right horse and rider pair, you can go without panels for an even more close-contact feel. Do be advised that you are removing some of the saddle’s weight distribution capability by removing the panels and may be putting some pressure on the spine; be sure your horse, pad, riding skill, and riding plans are not going to cause back soreness.
