Thats the weight that is quoted for a Large USGI Alice Pack, Frame, Kidney Pad, and straps. Which is my do it all "longer hikes, trips, and hunting" pack. I might be out of my mind, but it works well.

I got a lighter pack, 1/3rd the volume (1,500 cu in vs. 3,800 cu in) and no metal frame but its made out of heavier 1000 Cordura Nylon and in general overly built, then the thiner ALICE pack materials. Not sure what that weights out to probably about 2-3 pounds.
