Pay attention to the specifics of an achievement - some only count toward the unlock if a drop comes from an activity directly.

From Walkscape Walkthrough
  1. The Backpack gives an additional +4 inventory slots.
  2. While wearing the Backpack you can carry up to 32 stacks of items without being overencumbered.
  3. If you have 31/32 slots with items in them, and you unequip the Backpack you will suddenly have 31/28 slots full and become overencumbered.
    • This can be useful for Traveling as it is unaffected by the overencumberance penalty allowing you to fill your inventory up to 32 then equip an item that benefits traveling for the trip to a bank or refinement station.
