I've used the SLR sling when I'm out and about. It holds all my camera accessories, and even has a little zipped cell phone pocket conveniently located at the bottom of the shoulder strap.
I absolutely adore the inset... hammock? that holds my camera securely in place without having to remove my zoom lens. The tripod straps are perfect, as is the idea of a strap to go around the waist so I don't get strangled every time I bend down to examine something.
This bag is very sturdy and constructed of quality materials made to last.
But there's a down side.
As a woman of average height and petite build, I find my shoulder is not broad enough to seat the wide strap of this bag comfortably. This causes the whole bag to sit off-balanced the entire time I wear it, and I'm often chafed at the neck after I've worn it for a short time.
If you're a smaller person like me, I do not recommend this bag.
