Two things. First of all, nobody makes leather saddles the way we do. Traditionally, leather saddles are soaked in water, cold-molded at room temperature to the proper shape, and then baked in an oven. This style of saddle making produces a very hard leather top that can take years to break in. Our saddles are hot-molded dry. No water. This produces a much more pliable leather top that conforms more quickly to your unique shape. Hot dry molding alone is an impressive innovation but we didn't stop there. Our patented Flex-Fly slot has inverted rear wings that allow your sit bones to push the leather out of the way as you ride. This technology which is unique to Selle Anatomica reduces perineal pressure, sit bone pain, and saddle sores.
