As a traveling videographer using primarily DSLR and mirrorless cameras to document arts events, I've tried every type of bag to bring a small kit of equipment to a gig. This is the only one I will continue to buy for myself and my team. The modularity isn't a gimmick. It's an essential feature that I use all the time. There's also a hidden essential feature of the Covert if one travels with a camera through airports: it's a discreet bag that doesn't scream, "this bag contains a camera!" In other words, it lives up to its name of being "Covert." I also travel with Pelicans and I find myself getting a lot of glances from strangers who know that whatever is in a Pelican is valuable. With this bag, neither my fellow travelers nor TSA/customs are curious about the contents. I can blend in with the other tourists and get straight to work! The only thing to be careful of is not to overstuff the laptop sleeve and stress the zippers. I tend to carry my 15" laptop, iPad Pro, and lots of paper documents in that sleeve and the stress on the zipper causes failure. But that's my bad!
