The fabrics of the backpack are mainly PU, canvas, cotton, Oxford, cowhide, polyester, denim, PVC, etc.
The canvas backpack is very durable, even if it is scratched with a small knife, it will not break very much. However, the rucksack is a casual style and is more suitable for casual clothes.
Leather backpacks generally use cowhide, sheepskin or ostrich skin, crocodile skin and python skin, etc. The leather bag has a good texture and is very resistant to dirt, but the price will be higher.
