I bought this bag to provide an alternative (either around my waist or over my shoulder/under my arm) to the over-the-shoulder bag I bought two years ago. Both are extremely well made, highly functional and - based on the first bag - wear extremely well. This one probably has a slightly smaller capacity, although exactly how you pack it is important. The reason I bought it was to provide a secure place for my valuables when out running, which it does admirably without bouncing around all over the place, but I'm also using for shopping and just pottering about when I don't need to take too much with me. Highly recommended.
