Sleeves of Storage (Greater)

This loose robe has wide, voluminous sleeves that each contain an extradimensional space. These spaces each function as a spacious pouch that can hold up to 5 Bulk of items (for a total of 10 Bulk), though no individual item can be of more than 1 Bulk; the sleeves grow slightly heavy as you reach maximum capacity. You can add or remove an item from a sleeve with a single hand free as an Interact action. If a sleeve is completely empty, you can place your own familiar into that extradimensional space. It can survive comfortably in your sleeve for up to 1 hour, after which it begins to suffocate. While in your sleeve, it can't be affected or targeted by any effects, but you don't benefit from any master abilities. A familiar can exit the sleeve of its own volition with a single action that has the manipulate and move traits. You can't place any other creature into your sleeves, nor can you place your familiar in a sleeve if it's larger than Tiny. If your familiar is in your sleeve, you can't place any items in the sleeve.

Each sleeve can hold up to 20 Bulk of items, and a familiar can survive within a sleeve for up to 4 hours.
