This is a great bag, even beyond photography. Plenty of room for a flagship and some lenses. A D4 with a Nikon 70-200 fits snugly into the side pocket with plenty of room for a D7100 with an 18-105 3.5-5.6 in the top. The inside is fully customizable so you can have it with or without dividers. The side opening is only accessible if you wear it over your left shoulder, but you switch the bottom of the strap to wear over either shoulder. Lots of MOLLE straps and internal mesh pockets.

The color is slightly darker than the picture shows, but well within the spectrum of being classified as Coyote.

Downside is the mesh lining the access on the side doesn't have velcro, so when you open it items inside can easily fall out. The two front pockets are easily accessible through, so putting the cards and lenses in there is a much safer option.

I purchased and returned this. It is EVERYTHING they say it is and as good as all the reviews here, and on other sites. Very compact and durable. The velcro dividers were VERY strong. Just enough room for a couple lenses and my K3II, with plenty of extra room for cables, batteries, filters, phone etc. Was going to use molle pouches for flashes. If this was just an inch or two wider, an if it was designed to be used as a backpack first, I would buy again. I just didn't like how it felt as a sling.

I like to photograph wildlife and landscapes and I spend lots of time in the mountains of Montana walking, running and crawling through treacherous terrain - I pack my D3300 and D7200 with 3 lenses a tripod, a monopod, spare batteries, cleaning equipment and lens filters. When it is packed like this, it is full; but, not bursting at the seams and everything is quite accessible at a moments notice - my equipment is also well protected by the padding. The pack is made of solid material that is very tough AND I do not notice it when I need to pay attention to my footing and the terrain around me - I own many high quality packs and this is my choice for when I am going on serious photographic hikes in the wilderness. This is a very well thought out pack. I will be looking at Hazard 4 whenever i buy packs in the future.

Pretty much everything from Hazard 4 is of excellent quality and this is no exception.

I use this with the Jelly Roll Lens/Scope/Bottle Padded Case for my camera kit - 6D, four lenses, and full kit including 6 batteries, dual charger, filters, hoods, flash, etc. It keeps my very expensive glass and body nice and safe. This and the regular Recon pack are my go-to bags - easy to use, super durable, comfortable, convenient, etc. I'm not a pro photog - I "take nice pictures" - so I don't know if this is truly pro grade. What I do know is that I beat the snot out of most things I own, and this pack (and my regular recon) ask for more. Got it dirty? empty it out and throw it in the washer - done. need to run off fast? it has space for the full kit and is ready to roll. I have not seen or used anything better.

Note that the Jelly Roll is necessary for carrying larger lenses like the 100-400 and it straps right on, securely, in about one minute.

I bought this bag to replace a Think Tank Airport Ultralight I've been carrying for the last several years. I wanted something I could travel with and be comfortable carrying around on vacation. I also needed extra room, as my photo kit keeps growing.

Here's what I carry:

Canon 5D Mark III + battery grip
100-400mm zoom
24-105mm zoom
8-15mm zoom
180mm prime
speedlite
GoPro + mounts
assorted camera care items (sterile wipes, caps, dust bulb)

Carrying all this stuff in my old bag stretched it's limits. I liked the MOLLE webbing on the Photo Recon's design. I figured I could attach an external pouch or two if I needed the room. There is a variety of pouches to add on from Hazard 4, but I didn't order any. The bag itself would be fine for a similar camera without the battery grip. Mine fit, but just barely, and it made it hard to pull out. Also, the movable inserts that allow for customization of the internal sections don't provide much in the way of being sturdy. Not sure that description was clear, so I'll illustrate with my issue. The DSLR body with a shortish lens attached pushed the dividers down during carry. The result is the rig is deeper in the bag after a while. The side flap access was handy for lenses and such, but the flash would never fit with all the other lenses. The 100-400mm just barely squeezed in and only with the hood stowed.

The cross-chest strap was comfortable and seemed like it would be so for long periods of carry. But putting it on and getting it off was awkward. It has the quick-release, but you'd have to sit somewhere to use it or have a friend hold it while you fasten the clasp.

Construction was sturdy, padding was sufficient. I knocked off a star for the almost-fit and awkward carry strap. I would recommend this to someone with only one camera body (without battery grip) and a few lenses, or two gripless bodies and a couple of lenses. For the curious, I went back to Think Tank for their Airport Accelerator.
