Ditto. I did a week long photo tour of Yosemite with a LowePro Slingshot, which is the camera-bag analog to the Gear Slinger. It was miserable for long days of hiking and climbing. Even with the waste strap engaged, which minimized the sliding, it still wore on my shoulder. It's all about the weight and it's distribution. I use a Maxpedition Fat Boy everything from a diaper bag to a laptop bag, and think they are great. However, I wouldn't try to carry anything more then you might otherwise put in a fanny-pack style bag if you were hiking all day.
