👉 Leatheriness refers to the quality of a material that is made from animal skin or hides, which can be either synthetic (such as polyester) or natural (such as wool). It describes how well a material resists wear and tear, especially when exposed to water, heat, chemicals, or UV radiation. Leatheriness is often associated with high-quality products such as leather goods and clothing, as it provides durability, comfort, and protection against environmental stresses.
