A significant step-up from the leather backpack, this piece of gear- resembling a hiker's pack- would actually have it's own independent inventory window and act as a container that can be set down, lifted overhead, or placed in a cart in addition to its primary intention of being wearable (it could also be placed into a container, but not while full, much like a bucket). It would have a formidable carrying capacity of 4x6, but would drastically increase stamina drain while sprinting, or prevent sprinting all together.
Materials needed would include ~6 linen or hemp cloth, ~4 leather, ~2 hard leather, ~2 bone glue, ~6 wool (for padding of course), and ~3 metal bars for the frame (could be either any metal or hard metal at your discretion).
Additionally, it could have a dedicated slot in the inventory window for the matching Adventurer's Tent, seen here:
