I've tried a lot of Pacsafe bags looking for the holy grail, and I just may have found it.
This bag is slim and low-key enough that I can wear it on travel days and it securely holds my passport, wallet, phone, and other travel-day valuables that I need to keep on my body at all times. It also blends in enough that I can wear a jacket over it and airlines won't ding me for having an extra bag on me.
Then, at my destination, it is just big enough to hold everything I need as a purse; phone, wallet, collapsible shopping bag, lipstick and other small items, even reading glasses/sunglasses.
It's stylish, comfy, and goes with everything. The security features are amazing and don't add weight or bulk - and they reduce my stress levels about potential purse theft/pickpocketing!
