I'm in the market for a 72 hour bag for emergency situtations and was wondering what everyone thought would be a good choice. Price isn't really a concern as long as its within reason, I'm not looking to spend $200 but I'm not trying to cheap out either, I want something that I can depend on. I'd like MOLLE straps on it and the only other thing I really need is a "gray" look, by that I mean doesn't stick out or look like it belongs to a swat team. I'm not sure what size I want as I don't have much experience backpacking but I know that I don't want a 5000 c.i. rucksack. I appreciate any suggestions.
