While thin (and string) fabric, I used this to carry the 16-35 while shooting with the 24-70, plus the NISI Jerri filter pack for sunsets and landscapes in Acadia NP. Without padding, it is virtually weightless and I’m cognizant of what I’m carrying so careful when sitting down for lens changes or grabbing a new filter, or snack. Water bottle was strapped to the bottom. Comfortable sling padding. Perfect for my quick grab-n-go needs without needing the messenger bag or something larger.
The only issue is the one-way zipper; I wish they hadn't left out the two-way version found on the larger model, as it makes a difference depending on how you carry the bag. One more thing: nobody needs that handle—I cut it off both sizes.
I have been using this bag as my daily carry for the last few weeks, and I can say that I really love it. I wear it as a sling in the front, and it fits lots of stuff (more than I need on a regular basis, but enough room for a small jacket or water bottle of if I needed to carry them). I love the pocket in the back for my phone. The organization is really nice, fairly minimal and not bulky, but very usable.
A couple small things that slightly annoy me - on the main zipper compartment if you open it all the way, I’ve noticed I can’t zip it back up one handed - it seems like it gets “stuck” on the corner and I need to use one hand to hold the bag while zipping it with the other. And the strap - no matter how I adjust it, I can’t have the padded part over my shoulder without having the easy-to-open buckle on my back, since one side of the strap (buckle side) is much longer than the other. So it does make me a bit nervous to walk around with it. I will probably add a zip tie as someone showed on a tip video, even though it doesn’t look great.
