Encumbrance in Pathfinder 2 seems to be pretty limiting, and I always seem to run out of Container space long before I run out of Encumbrance space.
Backpacks can carry 4 Bulk worth of items, and Belt Pouches can carry 4 Light items each. Sheaths will hold your weapons just fine, but you're still not really left with much space to work with. If I max all of those out (assuming I can carry at most 4 Belt Pouches) I'm carrying about 6 or 7 Bulk worth of stuff. If I have 16 strength I still have at least 1 Bulk worth of space left to carry stuff. Wearing armor can fill that space, but how can I make use of that remaining Encumbrance without filling up my hands carrying sacks?
