I was wondering how Imago owners wear this bag. It appears to be a shoulder bag but I wonder if it's mostly worn on the side or over the head. I also wonder about the waist strap and how well that works. I'm interested in this bag but I dislike bags that bounce around alot. I might try this bag to store stuff as I walk the dog so comfort is important. I sometimes train my dog on walks to the park and for that I need both hands free to give signals.
