This is known as Carved version and it allows for a more flexible that alleviates pressure in the perineum experienced by some cyclists. This cut out also helps to make the saddle break in faster. There are laces on the side to keep the structure in shape and dial in the tension of the saddle, without these the leather flaps will spread out and lose their shape. There is a different width cutout for men (wider) and women (narrower).
