Material decides how a bag behaves after the first month. Leather brings polish and repair potential. Canvas is lighter but can stain at stress points. Nylon is practical, especially when weather and weight matter.
Choose by friction
If your week includes subway doors, laptop corners, coffee, and rain, the most beautiful material may not be the smartest one. Match the bag to the friction it will meet.
Smooth leather shows scratches faster. Pebbled leather hides daily marks. Coated canvas can be easy to clean but hard to repair. Nylon is light, but the hardware and straps still need inspection.
