Flesh Side of Leather

The flesh side of leather refers to the back or inner side of the hide. It is typically rougher than the smooth outer surface and has a more fibrous structure.

This fibrous structure makes the leather softer and more flexible, but also more absorbent and less resistant to wear. For this reason, manufacturers usually place the flesh side on the inside or further process it before using it as a visible surface.

What is the flesh side of leather?

The flesh side of leather forms the inner layer of the hide, opposite the smoother outer surface. It has a looser, more open fibre structure, which gives it a slightly uneven and textured appearance.

Because of this structure, the flesh side feels less smooth and less compact than the outer side. In most leather products, manufacturers place it on the inside, where it supports flexibility and helps maintain the material’s structure.

Even though it is usually not visible, the flesh side of leather plays an important role in how the material performs during use.

Processing the flesh side

Manufacturers treat the flesh side of leather in different ways depending on how they plan to use the material. They may leave it in its natural state, lightly finish it, or process it mechanically.

One of the most common methods is sanding or buffing. When manufacturers sand the flesh side and use it as the outer surface, they create suede (also known as velour leather). This process gives the leather a soft, velvety texture that works well for shoes, bags, and accessories.

They can also refine the flesh side further to improve its appearance or durability. The exact treatment depends on the desired look, feel, and function of the final product.

Processing the grain side

Manufacturers process the grain side of leather in various ways, depending on the intended use. It can be left in its natural state, lightly finished, or mechanically treated.

One of the most common methods is sanding or roughening. When the flesh side is sanded and used as the outer surface, suede leather is produced. This gives the leather a soft, velvety surface that is particularly well-suited for shoes, bags, and accessories.

In addition, the outer surface can be further refined to improve appearance or durability. The exact treatment always depends on the desired look, feel, and intended use of the final product.

FAQs about the flesh side of leather

Why is the flesh side of leather rough?

The flesh side of leather has a more open and less dense fibre structure than the outer surface, which makes it feel rougher and more textured.

How do manufacturers process the flesh side of leather?

They either finish it lightly or sand it. When they sand it and use it as the outer surface, it becomes suede with a soft, velvety feel.

Is the flesh side of leather used in products?

Yes, manufacturers typically use it on the inside of leather products. In some designs, they also process it and use it as the visible surface.

What is the difference between the flesh side of leather and the outer side?

The main difference lies in structure and texture. The outer side is smoother and more compact, while the flesh side is softer, more open, and slightly rough.

Summary of the flesh side of leather

The flesh side of leather is the inner and typically rougher part of the material, defined by its fibrous structure. While it often remains hidden, it plays an important role in flexibility and processing.

With the right treatment, manufacturers can also turn it into finishes like suede, making it a versatile part of leather production.
