Every bag I've come across is a right handed model, meaning the bag is intended to be carried so the clubs are carried on your right shoulder, or if using a dual strap, the clubheads point to the right of you. If you look at the bag from the front (so the handle is facing you), there's padding on the left side of the bag that rests on your body.
I've always carried it with 1 strap, and on my left shoulder. Can anyone recommend a left handed bag? I can retrofit the strap, but the design should have the padding on the right side of the bag. I destroyed my Callway bag and ruined a pocket because it rode up against my body.
