This winter I saw this intriguing item from Beis - the survival strap, which you can attach to another bag and has a pocket for phone and a card. Reviews say it's a bit short for many people though. And I need a new smallish bag anyway. During a couple of recent trips I have been thinking I'd really like to find such a thing, and have looked at a few airport shops and found nothing of this type.

Has anyone seen / or has - a nice, travel friendly small-to-medium crossbody bag with a wide strap with pockets for phone and a few other items?
