This is a type of leather that sits between the most common Pigmented Leather  (the most durable and used in the majority cars) and Aniline leather which is the most natural looking leather with the unique surface characteristics of the hide remaining visible. Semi-aniline leather is more durable than aniline whilst still retaining a natural appearance. The increased durability is provided by the application of a light surface coating which contains a small amount of pigment. This ensures consistent colour and imparts some stain resistance. The first Aston Martin cars that used semi-aniline leather was the DB9 Stratsone coupe from 2010.
