REI will make your wallet lighter for sure. I have an old external that has the same netting the atoms pack uses, and it weights 4 pounds, thats from 1975!
I tell the guys at REI that my base weight is 9 pounds and they say, "Oh your one of those minimalists?" I tell them no, i am not. I carry all the same stuff you do, just that most of it is lighter,made, and recycled. It also shocks them for the price of the atoms pack I can make almost all my gear.
