Pocket shim for closed panels

Can affect the rider's pelvis tilt, refines the twist, and slightly deepens the seat. It goes under the front of the seat, with the wide side toward the pommel and the pointy side toward the rider. It can be moved forward/back for a greater effect.
Riders who have a low pelvic floor may not like the bolster. For those who are looking at the product to tilt the pelvis, one of the other rider balancing aids will have a great effect without discomfort.
To install, release the velcro under the front center of the seat, then tug the seat back over the front dees. Place the bolster and press the seat back into position, making sure all is still symmetrical. Replace the front velcro tab and push the seat back over the front dees. This last part can be difficult, especially when the saddle is new - to make it easier, pull some twine or a shoelace through the dee to give you more leverage.

Velcro wedge to reduce seat size about 2cm (1/2-3/4"). It has a bit of cushion as well. To install, carefully pull the seat forward over the cantle. Don't go too far because there are velcro tabs at the bottom of the seat. Position the seat reducer as desired and press the seat back into place. You may need to lean across the back of the seat to push it down far enough for the velcro logo on the cantle to grab.

These stirrup straps are thin, yet very strong. Made from granite biothane, they'll hold up longer than leather but don't create a bump under your leg. Even better when you run the buckle at the bottom and use the handy keeper to put the excess strap neatly out of the way.
The standard configuration Ghost stirrup straps are 1" granite biothane and can work with any stirrup style. These are the only Ghost stirrup straps that work with the English slip-on fenders.

If panel shims aren't enough or you have closed panels, it's also possible to shim in the pads (although the pocket shims for close panels may be a better option for both cases). You want to make sure you are still using the foam pad inserts so you don't put a transition next to the horse, plus they'll stay in place better.
One advantage of the pad shims is that they are easy to put in place while the saddle is on the horse (not girthed) and can easily be removed if one horse needs shims and another does not.
