First, an iPhone pro max does not fit in the outer “hidden” pocket. And no other pocket inside the bag can hold it “secured”. One of the open pockets is sized ok for it as long as it can be a dedicated pocket. The inside pockets should be elasticized tighter so items can’t fall out or shift around as much.I struggle with placement of pretty much all sling bags. This one is ok. They tend to want to sit on my neck when tight enough to be against my back (meaning little to no gap with the back of the bag largely touching my back). This one gets to a bit of a middle ground. The stabilizer strap is really good. Once I use it, comfort basically skyrockets for me.I wish it had equipment straps like the backpack version of this bag. Being able to attach an ultralight folding camp chair or tripod to the outside would make it very functional.Other aspects are exceedingly well thought out. I love that the iPad/electronics pocket is a separate externally accessed pocket. There is even a pass through for a power bank in the main pocket. Handles on two sides. Etc. I may try the 10L bigger brother. That one has room for a 14” laptop *and* a 13” iPad Pro. But it’s all in the main pocket and this 6L version was already feeling a bit big for what I wanted.I am not sure I am keeping it. But, I won’t nay say it. Good bag. Possibly not ideal for me. It almost makes me wish I had the smaller iPhone as fas access to that is one of the major points of a sling bag to me.
