purchased it about a month ago (as of publication) and have been using it frequently, both for collage commuter trips and standard travel. The design of the backpack is great, but there are some notable issues that I think would be helpful to consider. First and most importantly, this backpack is not completely waterproof. You state that, but I want to elaborate on that. I used it four times in the rain. The first time I used it, it rained lightly. I was out for maybe an hour and a half and nothing in the backpack was wet, even though the outside of the backpack was soaked. The second time it rained moderately and I noticed a leak, but my electronics were not damaged. After that I started using the water cover and although it is a hassle to take it in and out, there were no “leaks”. As far as design goes, the interior compartment is fantastic. You can really customize it however you like, but it would have been beneficial to have maybe one or two more dividers. It wouldn't have hurt if the top pocket area also worked with the dividers. You can still move the main divider (between the top and main compartment) to create more space in the main compartment, but that does very little to help divide the top area. Still, I would give this backpack 5 out of 5 stars if it weren't for the straps. The straps are comfortable for a short time. But as the day goes on, you may feel a little overwhelmed and need to take a break (maybe 40 minutes to an hour after wearing it). In addition, the straps and back are not very permeable to air. I don't think there's a backpack that actually feels "air permeable" (to me), but this one is on the lower side of the rankings. Your back and shoulders will get very hot when wearing it, especially in the heat (of course), which is not helped by the fatigue you get after long trips. But if you can spend a few minutes taking it off and resting, this backpack will do just fine. I would say in terms of a saddle bag and a camera bag, this is a 5 star rating. The breathability issue will not be a problem as you will need to turn it on and off regularly while taking photos. But for a bag for commuting or everyday use it's 4/5. Ideal for carrying things (like any bag), but not for long periods of time.
