New Backpacks made from troll hide and/or silk with more storage. Thanks.

Inventory can already be inflated to 90 slots (more in case you compress eligible stuff using belts), plenty enough for the most dedicated packrat.

One could argue that the nomad credo inventory expansions should be turned into the ability to wear higher capacity backpacks instead of providing a permanent inventory enlargement out of thin air.
