Here's a yinrih wearing a backpack. He wasn't supposed to be so chubby but eh.

There are LOTS of pockets. They're sealed with magnet flaps. The main compartment opens from the rear, and there's a ring attached to a zipper to allow access with the tail.

I suspect the pockets on the chest are accessed with the front paws, and the pockets on the side are accessed with the rear paws, so items that you want to be immediately accessible would go in the chest pockets.
