Treeless and girth?

One more thought…

We also use the Nunn Finer non slip pad under my husband’s Bob Marshall. It’s fine on his QH and TWH, but I won’t use it on my Arabs, who both have fairly sensitive skin.

The larger size will work with a western or endurance saddle. http://www.nunnfiner.com/Nunn-Finer-Western-No-Slip-Pad-p/71w.htm

I have two Sensation saddles (G4 jumping and G4 dressage) and use their Self-Centering girth on both and have never had any slippage issues even on the few occasions I have had to mount from the ground. I like that the liner is removable for washing and comes in felt, neoprene, or wool fleece (I have felt) for whatever your horse finds most comfortable.
