Forgive my ignorance. I am interested in either a FlipBelt or a Running Buddy for my upcoming trip. I understand that you hold your phone in your hand through security, but why is there a need to put the Running Buddy in your husband's pocket?. Couldn't you just have it in place on your pants? I am really wanting to avoid bag checks this trip. But I will have more than my phone in my Running Buddy, such as a safe key, ID, credit card, small pill box, and lip gloss. Just wondering if I can have my stuff in there and it on my pants and still avoid bag check?
