Quevis

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, brown 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.
Add embroidery with your horse or barn name for extra fun!
I keep mostly black with various bottom materials in stock. Others will have to be ordered from Italy.

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 you prefer a webber style strap, check out the T-bar and Conway Straps.

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.

Wedged shim inserted between base and closed panels. Perfect for those who want the classy look of the closed panels (especially with a matching color/material) but need a little lift in front to balance the rider for horses who might be downhill where the saddle wants to side or who have less curvature than the Ghost base. These work great with velcro opening panels too, and sometimes are a bigger solution than the felt shims that can go inside the panel. This is also the best balancing solution for the western saddle. Sold in pairs.
