Okay, this is going to sound like a commercial-- but it's not-- I just love this thing so much that I have to share it.
Okay, the Burton Snowboard company makes the most comfortable camera bag that I've ever owned. Period. And I use it for everyday shoots, not just for travel and sports projects.
It was designed for Burton's staff photographers in the early 2000's, and has been available for the general public to buy for only a few years now.
