In the olden days, it was made from very soft leather, and took lots of care to keep supple. When I started cycling in the early eighties, most shorts still had leather chamois.
These days, they are all synthetic, and machine washable, and far superior. As far as I know, nobody is producing shorts with chamois fitted, but the name has stuck.
