When i got my new iPhone 7 i needed a few new carriers (!!). My favorite from Amazon has a large pocket for phone and a slightly smaller pocket in front of that for cash cards etc.  The bag has a snap on the flap but still felt a bit uncomfortable having cash and a few cards loose, especially when I would go to pay and full this wad of stuff out. This slim wallet has one side for visible drivers license/id, a strap to put some cash ( I usually have five bills folded and a few credit cards slip into a slot on the end....and all of that, still very slim.  I feel much more protected with my stuff.  Bought the orange so i an always see if it is dropped, hidden in bag most of the time so not concerned about clashing with colors ladies!
