If you don't need a shock absorbing pad, then just use a cotton square pad or a shaped fleece pad. Toklat's Coolback
fleece are both very nice for wicking sweat and some mild cushion. They come in all shapes and sizes, and the Coolbacks come in a variety of fun colors.
If you want something that's shock absorbing, I can recommend ThinLine Pads
, Skito Pads
, and Supracor Pads
. The ThinLine are the thinnest and least expensive (if you go with the Half Pad
or Contour Pad
). The Skito Pads are shimable and custom made, which is a very nice option! The Supracor pads are very nifty (a friend has one and swears by it), but pricey ;). I have both Skito and ThinLine pads and LOVE them! They really do work as well as they claim.
Sheepskin is nice, but not really that shock absorbing. It also adds bulk, which can change the saddle fit. If your saddle is a hair on the wide side, then sheepskin might be a nice option. I recommend Engel
, or Mattes
. Roma or other cheaper "off brands" aren't made with very good sheepskin. You want 100% merino sheepskin, preferably medical grade.
A nice wool felt pad isn't a bad choice either. Schooling Pad By Diamond Wool Browsing Store - Toklat Woolback Wither Relief Pad with Felt
