Breathability of leather

The breathability of leather

Breathability is one of the special properties of leather, which no other substitute material exudes. The ability to push out moisture in the form of vapour is one of the main characteristics of leather and what makes it unique. Especially in shoes, this is extremely essential. In warm and waterproof hiking boots made of leather, you will never sweat as much as in rubber boots.

The ability to absorb sweat and humidity, and push this out, is also noticeable on car seats and leather furniture and is better than on imitation leather.

However, breathability is different depending on the type of leather. Sensitive, porous aniline leather has a significantly higher breathability than heavily pigmented car leather. Also other quality features such as firmness, colour fastness, dirt resistance and overall longevity are important criteria for some applications of leather. For this purpose, the surface of smooth leather is protected by application of a colour layer against stains and fading. This improves the durability and long-term appearance of the leather, but significantly reduces the vapour permeability. However, breathability of such leathers is still substantially high when compared to artificial leather.
