My first pack was an airborne ranger kidney buster that I replaced with a Trapper Nelson (bright yellow) which I loved and had for over thirty years before it "disappeared." I am currently searching for a new pack, but there are so many good ones on the market, it is hard to decide. My wife and I are into the modified lightweight backpacking area (up to 30 pounds for me and 20 or so for her), so I would welcome some ideas as to best packs.
