If you're looking for a versatile, large pack to lug a lot of your gear into the woods or through an airport, this may be the pack for you. This pack is quality throughout, and there are more pockets and useable space than most of us will ever need. I own 5 DSLRs, and I'm able to fit 2 into the pack along with 3 lenses for each, lots of spare batteries, lens cleaners, filters and just about any other useful item I need. One of the greatest features is the very useful day-pack, which can come out of the pack and fastened to your waist. The added bonus to that is that you can use the space inside the pack (that you free up by removing the day-pack) for storing a snack and maybe a water bottle.The only con that I can think of for this pack, if you want to consider it a con, is that there is so much space that you can over-pack with too much photo gear and really bog yourself down. For that reason, you really can't go any larger in a photo backpack without making it too heavy to put on your back.One downside to most of these photo backpacks is that they're not on par with regular backpacks in terms of comfort, and this one is no exception. The shoulder and waist straps are thinner in comparison to those on a quality, regular backpack. And if you load the pack with lots of heavy photo gear, it tends to sag and the straps will dig deeply into your shoulders.But if you don't load it down, its fine for most photo backpacking duties. So, why did I give it 5 stars? Well, quite simply put, this pack is very low in price in comparison to most professional photo backpacks, which can easily cost several hundred dollars. You really can't get much more bang for the buck with this pack. For what you're paying, this pack is excellent.If you're looking for a backpack to store a single camera and a couple of lenses for a long hike in the woods or an overnight stay, you may be better off with a traditional backpack and a 'photo insert.' That way, you can take a sleeping bag, small tent, food and a basic photo setup. For an overnight trek like that, I use a Kelty Coyote 80 with a photo insert. The utility of owning both backpacks is that I can tailor; selecting the right pack for the situation.In summary, this is a great pack, and I wouldn't hesitate to recommend it to anyone.
