The PU leather we chose is one of highest quality materials. Under normal usage, the Zero-G should be able to last at least 3 years without peeling. However, this varies depending on your environment and how you handle the backpack.
There are also paddings in-between the exterior PU leather and the interior lining of the backpack. This means you don't have to worry about stretch marks or the backpack losing its shape.
PU leather requires very little maintenance such as cleaning and wiping dirt or dust from its surface. It is not only dirt-resistant but also water-resistant. As long as you are not soaking it into water for a long time, it will keep your items dry and safe. However, the backpack is not machine-washable. To clean it, you can simply wipe it down with a damp cloth.
