The lifespan of a leather strap depends on the type of tanning, daily use and maintenance. A quality vegetable-tanned calf strap, worn in rotation with other straps and kept away from water, can last between 3 and 5 years whilst retaining structural integrity and developing a distinctive patina. Milano Straps leather straps carry an 18-month guarantee against manufacturing defects.
