This is a great pack. I bought it for an emergency prep/72 hour kit I'm putting together, and just recently had the opportunity to test it out on a two week trip through Europe. I gave it a fair share of abuse throughout the trip and did not have a single problem with it. Main compartment is large. It will hold the 100 Oz. Hydrastorm in a separate section of the main compartment. There are tons of molle attachment points which are useful, and the pack is very adjustable to make it comfortable to wear no matter how much you have stuffed into it. Zipper pulls are nice and smooth, D-rings on the the straps and key adjustment buckles are metal instead of cheap plastic. Overall a great dependable pack for the money. A side pocket on each side might be nice, but there are two adjustable straps on each side of the pack that can be used to simply cinch the bag and make it thinner as well as hold a jacket or bedroll etc securely without worrying it will fall off.
Pros: Durable, Rugged, Molle Attachments, Easy to use
Cons: No side pockets
