The Aqua Aniline leather is a full-grain Italian lambskin, drum-dyed to achieve a deep, rich color and a subtly lustrous finish. The leather is immersed in an aniline bath — a transparent, non-toxic, and slightly oily water-based solution derived from a blend of various resins. This process allows the dye to fully penetrate the hide, resulting in a rich tone while preserving the natural grain and unique markings of the leather. It is then treated to provide water-repellent properties.
