I had to look up the lockable zipper thing to see what that is. It doesn't look that much safer to me than using a split key ring or carabiner for the same purpose.
The Baggallini bags I have do not have anything like that. They do have other ways of securing things inside.
I really don't worry much about that, though. The only things I carry in my handbag besides tissues, cough drops and some cash, are my phone and emergency information. My phone is the most valuable of those, not because it's an expensive phone but because of the information on it. Everything else is in my money belt. I do not carry any kind of wallet.
I must admit that I'm a Baggallini fan, maybe even an addict. I just counted and I have 17: 5 large totes and 12 handbags of various sizes.
I do love the colors. Those of the small and lightweight handbags I take to Europe include black, red, gray, Pacific blue (probably the great blue others have mentioned) and Juniper green. I'll either take a black one or the Juniper one to Ireland in May.
They are all cross-body. I'm right handed, but I put the strap on the right and the bag on the left. I usually put the zipper pockets facing my body. If the bag is too low, like down to my hip, it flops back and forth. I have to wear it much higher. I guess that must have something to do with the way I walk.
