Poor zippers, key flawa
"Ok, not great. Zipper layout (many curves) is already causing zipper issues, I don't expect them to last a year with regular field use. Internal layout of pockets is great. External water pockets are small and will get stretched/busted quickly with regular size 1L bottles like a nalgene. Top compartment access is decent, but the inside zipper pouch of it is a poorly located (zipper requires top compartment to be fully flipped down and open, instead of easily being accessed with main zipper only partially open. Main material of pack has almost no water resistance, but the good tradeoff is it blends in well, and is quiet. Overall there are a few key things that keep it from being a good or great pack. I would not buy this one again now that I have it in my hands. KUIU tried unsuccessfully to reinvent features and layout that have been solved long ago in the name of looks."
