I've been loving K&F Concept products, but this is perhaps the largest item I've used from them (most are SD cards and small photo accessories).I'm quite impressed by the overall quality and organization options with this backpack. It seems well-thought-out, and I'd gladly recommend it.The outer material is a soft and leather-like, but it does feel durable and can be wiped clean.The main compartment includes various organization dividers, which can be configured in an unlimited number of ways.I've had zero issues getting my DSLR, bridge camera, and spare lenses in the main compartment with room to spare.The padding is decent, and the inclusion of a padded laptop sleeve is something that any professional photographer will appreciate.Included with the bag is a raincover, which I thought was a nice touch.The side-access opening is genius, and while I've used other bags with a similar feature, I do give K&F kudos for including it with this bag.On that quick access opening are small pockets for SD cards, although I would have loved to have seen them stretch out a little, so they could fit spare camera batteries.The outside of the bag has adjustable straps, which can be used to hold your tripod, as well as a side sleeve for anything from a light meter to a water bottle.The shoulder straps are adjustable and quite comfortable. It does have a sternum strap, but not a waist strap, which isn't really needed here.One thing I do want to mention is that in the listing under "fully open back", it looks like the person has the bag on their chest and opened to access a camera. In reality, this is very awkward and not recommended. The front flap of the pack is too thick, so unless you enjoy having to use your chin to access your gear, just take the pack off and access it like you would.Finally, the top section of the bag gives ample space for lens filters, smaller grey/colour cards, a portable recording device, etc.Overall, I really love this camera bag. It's definitely not a budget option, but for the quality and feature set it's hard not to recommend.
