We spent 12 days in St. Maarten and I used this bag every single day.

For the plane ride it easily held both our passports, credit cards, money and various personal items (chapstick, eyedrops, etc.)
TSA didn't even blink an eye when it went through the x-ray either and I bet it must have looked bizarre since it has metal mesh through out.

I lengthened the strap to carry it across the body and it was comfortable at any strap length.
All the security features were great but the best was the RFID protection! IT protected our passports and credit cards from being secretly scanned.

During our time on the island I carried an iPhone, Cannon smart pix, Garmin GPS, credit cards, cash, chapstick, etc.... and I still had plenty of room in the main portion of the bag.

We plan on going to Paris next year and this great little purse will be going with me!
It's even perfect for everyday use, if you so choose. I'm thinking about buying more Pacsafe purses in a variety of sizes and colors. *grin*

I got mine in basic black, so it matched everything.  :)

Great little purse for easy travel experiences.
