The K&F 20L Nature Wonder is a flexible camera and day bag, constructed from shiny, weather-resistant polyester with smooth, quality stitching and glove-friendly zipper pulls. For added protection, a stretchy rain cover is included inside.

This bag excels at versatility. It works as a dedicated photo backpack but quickly converts into a commuter bag. The roll-top expands, adding an extra 20cm of height for storing a jacket, lunch, or work essentials like a laptop, cables, and paper. There are multiple internal organizer pockets for smaller gear like batteries and memory cards, plus side pockets for a water bottle and a dedicated dual-strap system to secure a tripod underneath.

Access is flexible, allowing a quick draw via the side opening (sling style) or full access and configuration through the secure back panel, which is a great anti-theft feature.

The bag includes five dividers and two elasticated straps, allowing for multiple configurations. While vertical storage works for smaller lenses, my larger lenses needed to go sideways. I was able to comfortably fit my R5 with a 70-200mm lens attached, plus two additional lenses, with the side door enabling easy access to the camera.

In terms of comfort, the back and shoulder strap padding is excellent. The straps cinch well to prevent bouncing, and the removable sternum strap helps shift weight. I took it on an 11km hike in the Peak District and experienced no pressure points.

The 20L Nature Wonder is a good value, comfortable, smaller camera bag that kept my gear dry during a small downpour and was light enough for a longer hike. It successfully carried enough camera gear and a tripod without feeling heavy.

I had reservations at first. The main camera compartment opens from the back, against your body, which was a first for me after years of using front-access camera bags. Instead of returning it, I loaded up my gear to test comfort and usability.

Here’s what I packed: Fuji X100V, DJI Osmo Pocket 3 creator combo, DJI Osmo Action 4, tripod, selfie stick, and several tech bags for cables, adapters, and small components I didn’t want loose.
After customizing the dividers and setting up the layout, I took it out for a full day of use. It performed better than expected. I could access my Fuji from the side pocket, and my 24oz water bottle stayed secure in the elastic side pouch that also held my Black Mist and CPL filters. The roll-top design grew on me quickly. It adds massive capacity without interfering with the camera gear compartment, offering up to 14 inches of deep cargo space for extra items.
While exploring a small town with my daughter, I was able to stash two of her clothing purchases in the roll-top area and adjust the ribbon for extra space. That kind of flexibility is something my other camera bags don’t offer. I now use this as my all-in-one weekender: camera and video gear, a padded laptop sleeve, two days of clothes, and my shave kit. The material is synthetic, water-resistant polyester with a subtle sheen that looks great.

Some Quirks: The dividers have a design flaw. They’re all pre-shaped and not square or rectangular, which limits customization. Worse, the Velcro is placed on the same side for every divider, forcing a uniform orientation. Also, not all interior walls are lined for Velcro, so some of the suggested layouts in the included booklet aren’t even possible.

Final Thoughts: This bag isn’t perfect, but it’s far better than I expected. It’s comfortable to wear all day and offers smart separation between camera gear and general cargo. I may finally stop searching for the perfect bag

This backpack has made carrying my camera gear a breeze. Loads of room for lenses, accessories, and my laptop, yet it doesn’t feel bulky on my back. Roll-top design and front pocket are great for packing efficiently, and side access means I can grab the camera quickly without unpacking everything. Waterproof material keeps everything safe in wet weather. Comfortable straps and solid build make it feel reliable, perfect for both daily use and longer photography trips.

This product was sent to me for review as part of the Amazon Vine program. The following reflects my real-world experience using it.

I requested it because I have a Sony A7Riv and FE 400mm lens that I like to carry combined, for convenience, so a large camera bag is essential.

It is a good-quality bag with a durable feel and a high-standard finish. The customisable straps are exceptionally well-padded, ensuring a comfortable fit.

I do feel that some areas of the bag's design are a little weak: the strap that holds down the roll-top compartment is too smooth and only secured by a single buckle. I observed it slipping out of place several times, which could result in the roll-top popping open unexpectedly - not ideal for protecting precious equipment. Also, the lower left side portion on the inside of the backpack does not have the same material as the right side, meaning that the hook and loop dividers can only be used on one side. It seems a shame that both sides can't be utilised equally.

I had no issues fitting various pieces of equipment (like batteries and chargers) alongside my camera and lens, and even though there was some space left over in the top portion of the bag, when I put it on my back, I didn't feel as if anything was wobbling around - the dividers are pretty sturdy. I would also say that the weight was distributed evenly on my back.

In summary, a reasonably useful and good value item, with some room for improvement.

+ good protection against water as well as build quality
+ strong structure and shape retention
+ smart organization and access (camera can be taken out from one of the sides of the backpack)
+ comfortable
+ does not look like typical camera bag/backpack

- not 100% waterproof
- layout and size might not be good for telephoto lenses
- limited organization
- too heavy and bulky with all the stuff inside
- many weak points (zippers, seams, magnetic flaps)

This incredibly well made back pack has space for just about every piece of kit you can imagine within expandable pockets, pouches and the main bag compartment itself, which is accessible both from the top and the rear of the bag. Everything is well padded to ensure the contents are kept safe and there is still sufficient space for tablets as well as camera equipment.

The bag includes a good assortment of partitions with heavy duty Velcro attached enabling customisation of the space to suit requirements. Some suggested layouts for the Velcro are included on the attached label, a sheet inside and also in the product listing, so you have starter suggestions for 10 if you are unsure how to structure the interior. I like the flexible straps that ensure your equipment stays within its allotted space no matter how rugged the terrain you are crossing.

The straps are very well padded and are, of course, fully adjustable to fit. Everything just feels very well thought out and the inclusion of a rain cover is a nice extra touch.

It is a great bag that arrives boxed ready to gift.

K&F hit it out of the park with this 1! There was a whole bunch of stuff that I daily carry in my camera bag. Batteries, drone, lenses, dji rs4 mini (with some attachments), some grips, lens filters, extra wires, ect... to my surprise EVERYTHING fit in it. Did it fit to where the backpack was comfortable to wear for hours? No.. not at all. Not the bags fault though... it was user error. Too stuffed. There were things bulging out of it as if I stuffed an elephant in it. However if I were to take the gimbal out everything fits perfectly. No bag bulges. Straps fit without a problem. Nothing pushing into my back. But then I realized I now have to have 2 bags instead of my original 1 bag. For cases where I don't need a gimbal its a perfect bag. Makes a nice simple day bag. It comes with partitions for the bag and you have the freedom to insert them and mold them however you want. The bag is very well built. Strong and sturdy. Comes with its own rain coat for the bag. There's a lot of compartments for you to put things. There's even a dedicated spot for you to put memory cards. Overall this is a really good camera backpack!!

This backpack is one of the most well-designed pieces of gear, in the camera world or not, I've ever had. There are multiple waterproofing mechanisms: waterproof fabric, waterproof zipper, ROLL top (which should've been good on its own), and even a rain fly!! There is very little chance that your gear's going to get wet with this system lol. Love the customizable inner compartment dividers, and really appreciate the divider option diagrams it comes with. Everything is just so well thought through. The side compartments have inner compartments. There are pockets galore. Love the roll top *as well as* back zipper for a suitcase-style experience too. Makes grabbing or unpacking super easy. My favorite part though might be the tiny, perfect pockets for SD and micro-SD cards. They're perfect for keeping your sd cards right where you need them, instead of getting thrown around in larger pockets. Really can't say enough good things about this backpack. I think it's well worth the money, especially with the coupon.

The only thing is I wish there were more overt storage options for multiple camera bodies, but you can definitely DIY your own compartment divider setup for that.
