I have a Pacsafe Slingsafe 100 (black). I feel very secure with it. Mainly because of the zipper lock. No, its not pickpocket proof, but I think its more of a deterrent. Move on to someone else whose purse has no zipper lock on it. I like the idea so much, I've purchased very small lobster claws and use them on my backpack zipper pulls. Its an Eddie Bauer with no zipper locks.

The Slingsafe 100 is almost too big sometimes. I end up just carrying junk. I would like to carry a smaller one. I don't need anything big. I still use an Iphone 5, so thats small. Carry a credit card, cash, room key.
