A quality leather strap has an average lifespan of 3 to 5 years with daily use, considering the natural wear of the leather due to sweat, sun exposure and repetitive movements. Vegetable-tanned leather develops a natural patina that characterises time, whilst chemically treated leather maintains a more stable appearance. Milano Straps vegetable-tanned straps are guaranteed for 18 months and are crafted to last over time with minimal maintenance.
