I've had a Kelty Red Cloud for a long time. It is a 5600 C.I. pack and is about 5 pounds empty. It will carry a huge load and is durable. Obviously not into the ultra light philosophy.

I don't get time to get out into the woods as frequently as I used to so when I head out it's usually a week or more so I gotta carry a lot. Not a huge mileage guy anymore just head out sans schedule other then when I gotta be home.
