Fanny pack/sling recommendations

I’m looking for advice on selecting a fanny pack/sling for a trip around Europe this summer with these specifications:

- Can be worn slung across the front of my chest for safety

- Is comfortable to wear for hours at a time

- Can hold a regular sized plastic water bottle, phone, sunscreen, wallet, etc.

- Has an internal zipper pouch for keeping my passport/important documents secured

Thank you!
