Convention use is different from daily carry. You need a bag that handles: That means the best convention bag usually has:
- long wear time
- crowded spaces
- repeated opening and closing
- heavier-than-normal carry load
- more risk of pins getting bumped
- a secure zipper around the display window
- enough depth for essentials and merch pickups
- comfortable straps
- a stable insert
- a size that does not get in everyone else's way in artist alleys
