Prisana's Practical Pullover

Wondrous Item, Uncommon

After The Event shrouded the western region of Jhilal in perpetual twilight, thousands of its people emigrated to the eastern coast of Pirra.  Among them was noted Conjurer Prisana an-Fel, who was so  disgusted by the impracticality of Pirran women's fashion that she dedicated five years of her life to solving the problem of convenient storage.

This hooded pullover is woven from the silk of a now-extinct moth.  The tunic falls below your knees, and bears thirty different pockets.  Each pocket connects to extradimensional storage, and each pocket can hold up to one cubic foot of material that weighs up to one pound.  Any item stored in a pocket can be retrieved as a bonus action.  If a pocket is left empty overnight, it will fill with a pound of sand from an unknown source.
