Herman Oak and Natural Veg-Tan leather in particular develops the best patina over time. This is because they naturally absorb the world’s elements, sunlight, and the natural oils that your body produces. These types of leathers are the highest grade and of the absolute best quality. They are considered the most durable and robust form of leather as they are made from the strongest part of the animal skin. In addition to this durability, they are often recognized for their attractive quality due to the close grain pattern. Totally undoctored, unlike split leather, this leather retains the natural markings of the cow. This is why, when they are naturally rather than chemically tanned, each develops a perfect patina. All of this contributes to creating a characterful leather and each piece unique.
