Ultra-lightweight and shaped to fit the saddle and help keep it from slipping.
Saddle slippage can be indicative of a badly fitting saddle and it is best to get it checked by a saddle fitter.
Place it directly against the back to stop both saddle and saddle cloth moving, or use under the saddle if the saddle cloth tends to slide out. For maximum saddle stability for cross-country or showjumping, sandwich the saddle cloth between two of these pads.
