I bought this for a trip to South America.  I was able to wear this under my clothes and you couldn't even see it.  Lays flat. I wore it off to the side.  Gave me piece of mind that if someone tried to take my purse, I had a backup emergency stash under my shirt.  Also very handy to use at the airport.  Even fit my iPhone 6 Plus.  Has many pockets, which was helpful to keep things organized.  Holds coins, cash, credit cards, phone, paperwork.
