1. The leather surface is bright and smooth. The appearance is smooth and smooth, and the texture is plump and delicate. The texture is firm and elastic when touched by hand. Smooth leather has good tensile strength, dirt resistance, wear resistance and good air permeability.



2. Pu is made of textile or non-woven fabric. It can be made of polyurethane coating and special foaming treatment. But air permeability, wear resistance, cold resistance are not as good as leather.



3. Compared with PU leather, leather has the advantages of more wear resistance, greater tensile strength, softer leather and better air permeability;



4. Compared with genuine leather, PU leather has the advantages of lighter weight, waterproof, less swelling or deformation after water absorption, environmental protection, lighter smell, easy care,
