Someone needs to produce a flying vest with lots of pockets like an anglers vest. Somewhere for phone, kindle, headphones, toothbrush, tablets, glasses, wallet, water bottle, passport ... Get it FAA approved for use on evacuation slides. It would be handy for passing through security when you have to empty your pockets as well. Just dump the whole vest in the tray. All the passengers problems solved except for looking like a dork !
