For me, this bag holds the following items without any MOLLE expansion pouches or jelly rolls: 2 Canon 5DmkII pro body DSLR Canon 70-200mm IS II f2.8 L Lens with hood (usually attached to one of my two 5d's) Canon 24-70mm f2.8 L lens with hood Canon 16-35mm f2.8 L lens with hood 2 Canon 580 EXII flash units 12 eneloop AA bateries 4 Canon 5d batteries 70" Ravelli carbon fiber tripod (mounted to the side of the pack) 5 77mm lens filters 2 compact flash memory card cases Basic cleaning utensils Using two MOLLE jelly roles, and two 6"x4" pouches, I carry the following additional items: Cleaning supplies (lens cloth, rocket blaster, sensor swipes, sensor and lens cleaning solution) Fotodiox extension tubes (set of 3) 3 to 4 additional lenses, or, 2 lenses and a spare compartment for lens swapping/water bottle/misc gear Hazard offers a lot of great MOLLE attachements for this pack, which is part of the reason I bought it. The modular design allows me to adjust things for the given task. I do, however, need to be very careful with how much weight I actually load. More on this later. PROS: * Well padded * Carries lots of gear * Tough outer shell, provides protection from the elements and moderate water resistance * Well made, from the zippers to the pack design * Excellent organizational pockets, for memory card cases, lens filters, batteries, business cards, ID badges * Sling design allows you to access your gear on the fly without removing the pack * Long and narrow form factor is ideal for crowded areas, plane rides, or stow and go situations * One of the few genuine camera bags designed around the MOLLE system * Looks tough, and will definitely make you standout from the weekend warriors * Convenient and thoughtful placement of grab handles * Priced fairly * Excellent customer service from Hazard CONS: * Sling pack holds more than one shoulder should carry. With 30lbs of gear your shoulder will scream at you for purchasing this bag. Bad decision for people with weak backs, shoulder problems, or poor upper body strength. * Pack does not fit snugly against my back (the might be due to usage, but this pack could use a light frame) * No option for two shoulder straps, although the shoulder strap is well padded, and can be reversed if you start feeling the load * No hip harness * Pack has a tendency to bend a bit in the middle. Would be nice if it had more structural integrity, to stay flat against your back while in transit * No rain jacket or waterproof zippers, although pack design is moderately water resistant I have found * Main harness buckle is made out of plastic. I've broken two of them so far, although I've been very hard on this bag, carrying 30lbs to 50lbs for hours on end. That said, Hazard has been amazing in their customer service, and replaced them. They stand by their products * Main harness buckle lock can easily be knocked/poked into the unlock position, and the main harness will instantly come undone if you are carrying more than 30lbs or someone is pulling on your bag The Good parts: I've owned this bag for almost 3 years now. It's held up exceptionally well. For the first two years, this bag made it with me into every nightclub and underground party in Chicago, several times a week, as an event photographer. It's been to dozens of rough-shod electronic music festivals. It has survived a wide variety of abuses during that time, from drinks being dumped on it, to being shoved around into walls, and even hitting the ground on a few occasions (with my body still attached to it, no less). All the while keeping my $14,000+ photo gear safe. It's slim form is great for dealing with crowds and maintaining a low profile while shooting on stage or in the pit. Comparatively speaking, the lowepro bags I own (which have also held up well) make me feel like a turtle while trying to move through a packed venue. Having the sling, while a negative in some respects, allows me to flip the bag around to my front side to secure gear and prevent pick pocketing in extremely crowded spaces. It's well-padded, and ready for the road. It fits into the overhead bins on an airplane, even when I'm the last passenger to board! This bag looks tough, and it is tough. Door guys often let me in, either by the dirty looks I give them, or because of how mean this bag looks. It also doesn't look like a bag full of photo gear (well, maybe with a tripod attached), so opportunists have less of an easy target. The Bad parts: My biggest complaint about this bag is the sling design. While good for some things, and visually appealing, it ultimately fails in balancing the load. I'm a tall guy with some muscle to my hustle; 6'3 210 lbs, and I've never had a back or a shoulder issue in my life. I can do 20 pull ups without breaking a sweat. However, this bag has broken me. My right shoulder had a dull ache in it for over 2 years. Even in my down time, I would go a month or two without using the bag, and my shoulder would still ache. Roughly six months ago, I switched the strap, so instead of resting on my right shoulder it now sits on my left. It's not as convenient on my left shoulder, but sure enough, my chronic right shoulder pain has completely vanished! I've come to realize that no matter how tough you think you are, there is no way you can carry 30 to 50lbs of gear on one shoulder, for several hours, and not wind up in pain the next day, or in my case, for months on end. During the Detroit Electronic Music Festival, I wore this pack pretty much non-stop, for over 12 hours a day. I was in so much pain by the end of the weekend, I could no longer sling it over my right shoulder. While the strap is nicely padded, that won't make up for the fact that you are carrying all of the weight your gear on one shoulder. Even if you only do two events or photo shoots a week, I would wager you will start to feel something from the imbalance this bag creates. I would give anything to have two slightly smaller but equally tough and well padded straps on this bag, perhaps with an option to turn one of them into a sling should I want to. It seems like it would be easy enough to do. It would be perfect; use two straps for walking, use one strap for field or event work. I like this bag so much in other aspects that I am considering paying someone $150 to modify it to my liking. This bag is great for travel, in terms of sticking it into tight places, but actually walking with it strapped to your back while fully loaded, sucks. Unlike an over-the-shoulder camera bag (which you can easily set down and pick up while you're not mobile), it can be a hassle to undue the plastic harness every time you want to take it off, and putting it back on will take some practice to do it smoothly. You can always leave the harness locked, and slide it over your head, although this would require undoing the safety strap. I've been buckling and unbuckling the main sling harness for 3 years now, and it's just not as smooth of a process as I would like (my wife, well accustomed to my ways, winds up a half a city block away from me by the time I get it buckled up). I've gotten good enough to be able to do it with one hand, but not to the point where I would consider this bag efficient enough for wedding photography... I have nightmares where I am chasing the bride and groom, two pro body dslrs in my hands, while trying to sling this pack over my shoulder.. I've also had issues with the buckle lock; event goers/party people/evil doers have bumped into me and either accidentally or deliberately hit the buckle locking switch, at which point, with over 30lbs in the bag, the sling completely unbuckles and the bag falls straight to the ground! The main buckle has a tendency to not stay buckled unless the lock is activated, at least in my case (although Hazard has confirmed that this is is a safety feature of the bag, which, strangely enough, makes sense to me). I had a drunk girl come up to me once and ask "what does
