1. A coated fabric comprising:
a base coating layer, the base coating layer defining a smooth coating to resist liquid penetration to the fabric;
a middle foam coating layer that is deposited on at least a portion of the base coating layer, the middle foam layer defining a middle layer foam density and the middle foam layer being configured to absorb at least a portion of liquid; and
an outer foam coating layer that is deposited on at least a portion of the middle foam coating layer, the outer foam layer defining an outer layer foam density and the outer foam layer being configured with holes to allow liquid to penetrate to the middle foam layer, such that the outer foam layer increases the abrasion resistance of the coated fabric,
wherein the middle layer foam density is from 0.25 kg/L to 0.60 kg/L, and
wherein the middle layer foam density is less than the outer layer foam density.
