To manufacture this Moto Guzzi V7 seat, we use an high quality double-tanned leather (chrome and naturel) that will get a certain patina over the time, depending on how you care after it. The foams are isolated from the leather cover by a plastic cover so it remains waterproof. 

Depending on the weather conditions of your country, an intensive exposure to the sunlight and rain will lead it to get a patina. It requires to be regularly maintain using leather cream and grease.
