Ok. I gave it 5 Stars, in reality they should have halves, because the pack is 4.5 Stars. 5 Would mean the best thing ever, and it isn't that, although, at $30.00 I think it's a tremendous value, So 4.5 rounds up to five. This bag makes the perfect 72 hour bag. I recently took it on a primitive camping, the trip was two nights and three days. And I would say, I really put the bag through its paces. The main compartment interior is spacious, with a divider for your hydration system, it easily accommodated my 2L Camelback, and due to the D ring on the shoulder strap, the Camelback straw stayed nicely in place. The main compartment easily housed three days worth of clothes and a waterproof bag, a full set of rain gear, a mess kit, and two canisters of propane fuel. Additionally, there's a zippered compartment on the interior, that held a full roll of garbage bags, and a full roll of 1 gallon Ziploc bags. The largest outside compartment on the front of the bag neatly held a large first aid kit, six chem lights, and various other small gear. The other front pouch held several aluminum tins for cooking/cleaning, and more misc. small gear. Each of the small pouches also held a considerable amount of gear. For example, one pouch held all my fire starting gear, which included a pack of cotton rounds, 200 yards of Jute twine, a magnesium striker, to Bic lighters, a folding magnifying glass, and a case of waterproof matches. So there are plenty of pockets, and tons of space in this pack. Additionally, each of the four small side pouches has a clasp, with webbing that was long enough to secure my tent to one side and my iso Mat to the other. I then hung might e-tool from one set of clasps and my hatchet on the other side. Th MOLLE webbing is a great feature, and is well-made. From the bottom webbing I hung my sleeping bag. the waist belt fit me well, I have a 34 waist, and it seemed like it could be adjusted to be much larger. it's made of nice wide webbing, and from it I hung my Camp Saw and my Leatherman. I mounted a Becker BK2 on the shoulder strap and it held nicely. The zippers are high quality, and the material proved to be durable. I hiked over 12 miles in three days with the pack, and it fit comfortably with at least 60 pounds in it. I would highly recommend this bag to anyone. Although I typically wouldn't use it for backpacking, it makes a great 72 hour bug out bag. Especially for the price.
