We went away for a long weekend and I wore my travel vest. I still used my travel purse because the vest is when I'm out and about. The purse is for use in the car, hotel, wherever. The vest worked perfectly. I loved not having to drag a purse around and not trying to jam everything in my jeans' pockets.
The vest is comfortable enough to not even notice it. I weighed it and at that time it weighed 3.5 pounds without the camera. My camera is small and doesn't weigh much but it stayed in my purse until I thought I might need it. The kindle also stayed in my purse most of the time but would fit in one of the pockets if I had felt the need of having it with me.
I even wore the vest over my housecoat because the earbuds and my ipod were so conveniently placed.
