TravelonUnisex's Anti-Theft Classic Waist Pack

Q: Where is the RFID pocket?

All pockets are RFID protected.

Q: Does this style have a water bottle holder

Yes, it has a bottle holder. There is a zippered compartment on the side that when un-zipped a small mesh pouch can be pulled out. Will fit a small water bottle.

Q: What size phone will the cell phone pocket accommodate?

I did not take my cell phone with me when travel abroad, but judging from the sizes of compartment would think that the phone of the size of iPhone will fit.

Q: Will it accommodate an iPad Mini? 51/2 x 8"

I tried my iPad mini with its case and it just fits to zip closed. I'm not sure if it would allow you to have anything bulky in the smaller pocket with it. I have an iPhone 6+ and meds and it works well.
