An aspect of the invention is a split leather product provided with a base material comprising split leather, and a skin layer laminated on a surface of the base material. The skin layer comprises a composite body of an entangled nonwoven fabric formed from microfine fibers, and a polymeric elastomer that impregnates the gaps in the entangled nonwoven fabric.
