This bag is a wonderful invention! My girlfriend and I have discovered for us because we wanted to have everything safely stored important on vacation and wanted to carry only food and drinks in the backpack. After some adjustments, the bag was perfect, if one has not made full, you could not recognize them under a cardigan. If you then still carried a normal jacket over it, she really was invisible and yet easily accessible, if you wanted it. The zip pockets are great for credit cards, the larger bag is good for ID cards - as long as you still have the old person. A iPhone 4 has fitted well in, but the mobile phone pocket for iPhone 6 was definitely too big. Absolute buy recommendation for all tourists!
