First selection bovine grain leather processed with a special waterproof retanning recipe
Endurance Leather COLLECTION
ASTICO DESIGN
Super Hydro
First selection bovine grain leather processed with a special waterproof retanning recipe, developed over the course of many years of experience. This process greatly enhances the dynamic resistance of water penetration and absorption of the leather. The very light finish adds a natural and elegant look to the leather. This article is suitable for the production of Gore-Tex® certified footwear and accessories.
