My first impression of this bag was it was smaller than I expected it to be, but the measurements do line up.What I Like:- The material quality feels good. It also seems to be water resistant, though it also comes with a water proof bag you can slip over it for when it’s a straight downpour of rain or something.- It has a good internal structure to it and doesn’t feel flimsy. It holds the structure even when empty.- It makes efficient use of its small size. No issue holding my DSLR with lens attached, plus an additional 2 lenses in the main compartment with some room to spare.- Several dividers to organize and keep things secure, so lenses aren’t bumping into each other etc.- I love the side opening zipper which gives fast access to swapping lenses.- There is a sleeve inside that can hold a laptop or tablet.What could be improved:- getting into the main compartment is not as quick as I’d like since I need to undo two straps and the zipper- the 2 main straps do not use click locking buckles, instead they have little plastic buckles that slide onto the straps. Sometimes the straps bunch up and get stuck which can be a bit frustrating. I would’ve preferred regular clicking buckles.- Feels like it could use one or two more external pockets to hold smaller items like batteries and lens filters. There is room inside for them if you setup the dividers properly but I want easier access.Overall it’s a nice backpack and keeps camera gear very secure and protected for travel, but sometimes accessing some of that gear isn’t as quick or easy as I’d like it to be in the field. The one quick access zipper is great, but it needs at least one more to be perfect.
