Bucking rolls. I honestly don’t know a ton about this product, as they’re not something I use- but one of my distributors told me they’re the hottest thing since sliced bread, so I bought a few pair. From the web:
“The bucking rolls are two padded pouches that are added to the front of the saddle seat to supplement the swells and help a rider stay in the saddle. They are designed to be used with slick fork saddles which have very little width to their swells. Bucking rolls are usually made of leather and can be quite ornamental and colorful.”
These rolls are quite firm, have thick leather and tight stitching. Available in a light or dark oil, see pictures.
