I currently own a PacSafe wallet and have been looking at this cross body bag for a while. I decided to get it once they came out with the all-black bag.
Having used it a few days now, I realize this will probably be best for just traveling and not everyday use. It seems to be the perfect size for me from the outward appearance. But there is a lot of bulk which creates very little room inside.
I find the biggest issue to be with the zippers opening from the bottom, upward. Every time I try to pull something out, everything else inside tends to fall out. The safety clips could have been put on the top of the bag so the zippers could be zipped from the top down.
I would feel very confident using this when traveling, going to concerts, taking day trips, etc. But it is too bulky for me to use daily. I haven't used it on a hot day. I suspect that the bulkiness of the strap will be uncomfortable.
So I will continue my search for a low profile, x-small, cross body bag that can be worn over the left or right shoulder, in all black!

Edit: After using this bag for 3 weeks, I can now say that I really don't like it. The strap never softened up. The bag is clunky and cumbersome, and I hate the zipper direction. I'm sorry I wasted so much money on this bag. I've gone back to using my old Eddie Bauer sling backpack.
