I bought this bag to use on holiday, but I've been using it everyday since it arrived. It's perfect. I carry either my camera or my Kindle in the back pocket and all my other goodies in the front inside pocket. What I love most is the rear zipper part. I keep my wallet there. No more digging in a bag to find it. It also leave my hands free when I'm shopping. There isn't anything about this bag I don't like.
It's waterproof (got caught in the rain) and I can even wear it just over one shoulder. It doesn't slide off. The cell phone pouch in the front is fabulous. Also, no more digging in a big bag to find it when it rings.
I ride a motorbike so this bag is perfect for me when I'm on the road.
