Saddle Sauce is our proprietary waterproofing formula. It is recommended for all saddles to protect the leather and prolong the life of the saddle. It can also be applied to any make or model of seat from Selle Anatomica or another saddle brand. Apply Selle Anatomica Saddle Sauce lightly at regular intervals, particularly to the raw leather edges and the bottom of the saddle. A thorough application of Saddle Sauce all over your saddles helps ensures proper waterproofing and extends the saddle's life.
