I don't have personal experience with the PA but I tested out some various items. I will probably only put my phone, mints, lip balm, and a smaller card holder that I haven't bought yet. Edit to add: everything fit and zipper closed without any issues. With my iPhone 11 Pro Max, it was at its max, but wasn't bulky.

Hope that helps!
