Very robust bag, Well made and durable. Zippers feel very solid, not going to break anytime soon. overall construction feels solid. Wish the cubes were included with the bag but it is what it is.Very nice well made packThey advertise it as a camera backpack, but then you get it and it doesn’t have dividers. After spending $250 bucks on the bag, you have to drop another $130 to buy the dividers to make it a functional camera backpack. It definitely felt sturdy and well built, but I sent it back because I needed a real camera backpack.What makes it what you want are the cubes and they can be put in any pack (not included) be advised the large is just that, LARGE. Being a pack rat I don't care for this design although I do like the heavy cordura and zippers. It handles a 3 ltr bladder with ease and a laptop, it's the outside. Not enough thought of d ring and molle strap placement, they're there but in the wrong places for me. I couldn't find a place for my nk 200-500 in lowepro case without blocking access or the gigantic side pockets and trying to add d rings. It wouldn't fit inside either, especially with the large cube and I really don't care for how the pack seals up top, (looks like it could possibly leak if you're not careful (yes, comes with raincover). Straps, hooks, loops or d rings are minimal towards the bottom. This pack is it big....but don't get caught up in the words (camera backpack). I am not a professional photographer, this review is based on my wants and needs, that being said it might be perfect for you .
