K&F ConceptI’m always on the lookout for a more functional camera bag that particularly has room to carry stuff in addition to camera gear so when this popped up on my radar I had to try it out. This is a very well thought out rolltop backpack with a couple of opportunities for improvement. Let’s take a look. I received the camouflage backpack for review and it looks like there are some significant design differences between the camo and the blue bags (placement of laptop sleeve and the type of cinch strap/type of buckle being the most significant).Design:This is a relatively straightforward roll top backpack with 2 front zip pockets (one is an RFID blocking pocket). There’s one main top loading compartment. Inside this main compartment there is a laptop sleeve that keeps the weight of the laptop against the wearer’s backOne side loading camera compartment. One the other side of the camera section is a tripod pocket and strap. The tripod leg pocket could double as a bottle holder if you’re not travelling with a tripod.One design feature to point out is that, if you’re not using the camera cube and just need to use this as a backpack, there’s a false bottom to the rolltop portion of the bag that secures with hook and loop strips. You pull this false bottom out of the way and have access to the entire main bag opening. This makes for a lot of carrying capacity as just a backpack.Another nice convenience feature to point out is the addition of an open nylon webbing loop on the back so that you can easily slide this bag onto the pull handle of a larger piece of rolling luggage when using this as your carryon.Build quality:This is a very well built pack. Zippers are SBS weather resistant zippers with round finger sized hi visibility orange zipper pulls. All of the zippers pull easily and freely.The material (per the product page) is a waterproof 900D nylon with rain cover. The interior of the pack is fully lined with a high contrast orange nylon that makes it easy to see what’s inside. The material does appear to have a light rubberized coating that would definitely make it water resistant in light rain. The roll top portion of the bag is not stiff as you might expect from a rubberized bag. It rolls up easily.In heavier rain I would definitely recommend using the provided rain cover because the access flap to the camera gear is relatively open. There are 2 zips on either side but there’s just a flap at the top so if you’re in a driving rain the weather could potentially get in.The shoulder straps are well padded and there’s a sternum strap to make things more secure. One of the straps has a quick release buckle at the bottom so you can secure your bag to something as a theft deterrent. There is no hip belt so this is not a bag for more technical or all day hikes but for incidental use it seems adequate. The bottom straps are made out of seatbelt style material. The top handle is padded and also a robust nylon material. The main bag cinch strap is nylon webbing material. It would’ve been a nice touch to also make this out a seatbelt material but it’s not bad quality. The cinch strap terminates in a cobra style buckle that is very robust and operates flawlessly.I’ve looked at every square inch of the bag I received and there are zero errant or loose threads. It doesn’t have the double stitched seams that you might expect to see in more outdoors adventure related packs but the stitching on the sample I received is immaculate. The bag looks and feels like it’s built to last. I’m very impressed.Camera storage:The camera storage is located on the bottom of the bag. There are 2 zippers tied together with a single nylon pull. I was concerned that this would get stuck when opening or closing this bag but the SBS zippers appear to be up to the task and the flap opens and closes easily. One item that they could add from a security perspective would be to have some kind of latch on the side of the bag, above the zipper pull, that you could latch to that zipper pull to. This could prevent accidental opening or opening by would be thieves.The inside flap of the camera section has 2 small pockets that are for batteries, SD cards, etc. These are just the right size for a couple of Fuji NP-W126S batteries each, with room to spare, as a point of reference. Putting the batteries in these side pockets did not in any way seem to impede the closure of the main compartment flap.The camera cube/organizer itself is made of a stiff orange foam with felt on the outside. There are 2 short dividers and 2 taller dividers that you can arrange anyway that you want. Once put together, this camera cube acts kind of like a drawer that slides in and out of the bottom door of the bag easily.It would be nice to have a few additional dividers. As sent you have the ability to potentially set this up so you can have a quick access section to store the camera on one end but have a more secure, boxed in end where you have your spare lenses. This is a great idea but I think they should send more dividers to accomplish this. As shipped the 4 dividers weren’t quite enough for me to optimally utilize the camera cube for my Fuji X-T3 setup. I slipped in an Ape Case camera cube and had enough room for my flash. BUT, then I don’t have the easy access to my camera that I just described. I’ll experiment with other dividers and see if I can make this a little more effective for my setup. It has the room but some additional dividers would make it easier to customize the layout for smaller mirrorless cameras.ConclusionThis bag has a lot of very nice features for everyday use as a backpack that also happens to have a decent camera carrying solution built into it. The camera storage could be improved. It would do well as a travel backpack or as a carry on. As a carry on it has an impressive amount of space when using the top compartment to its fullest. For outdoors use you could use this on day hikes but would likely want something a little more robust and purpose built for serious backpacking or hiking use.
