I really want to like this bag. Shape and volume is perfect. Love it. However, like a few bag-tuber have said in their reviews, the rain flap on the upper edge of main zipper really does make zipping up a pain. I believe part of the reason has to do with the unnecessarily stiff front panel, though I suspect stiffness is meant for the bag to hold its shape in case front pocket is fully loaded. Then there is my minor gripe wishing for lighter overall weight. I get that the material used are pretty solid, but I’ve already trimmed stuff down to 12L, perhaps the bag can trim a bit more weight/stiffness from placed other than the laptop compartment.
