Endurance Leather COLLECTION

ASTICO DESIGN

Dakar
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 classic oil and wax finish adds a vintage and very natural look to the leather. This article is particularly suitable for the production of technical footwear, fashion footwear and accessories.
