The best backpack..........well, that's very subjective; however, I'm in the market for a new backpack myself and the Badlands backpacks have caught my eye. I was at Bass Pro the other day and saw some there. Badlands are expensive, but are well made and conform to your body for a snug fit. They come in several sizes, althoug I only saw the 1900 c.i. model. The biggest negative is the price.
