Stirrup Holders

These slip on over girth straps if there is a bigger gap between the bottom of your pad and the girth (short flap saddles or larger horses). They can also be ordered with the top layer to match your saddle color. Backing options are neoprene, black, brown, or white wool blend (or exclusive sheepskin, but that's really more for show than practical use and typically order along with either a zalea or Cagliari/Maremma saddle.)
Sold as a pair.

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.
Keeper color/materials are found here.
If you prefer a webber style strap, check out the T-bar and Conway Straps.

Ghost makes an extremely nice pad, especially for the very reasonable price. Many people buy these for other saddles including BMSS, Freeform, and even treed saddles. Bottom material options include sympanova (a soft rubber, easy to clean, breathable), black or white wool blend, and an amazing medicinal sheepskin. I recommend 1cm inserts with sheepskin unless rider is over 185, and for other bottom materials unless over 165 or horse's spine is well protected.
I keep mostly black with various bottom materials in stock. Other colors will have to be ordered from Italy.

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.
