RE: Backpack List....OK??
everyone is giving you some sound advice.
i will add - having iodine pills (if possible) is much lighter than a filter. One bladder full for the hike up and one empty, fill the empty oneup and leave at camp. tent, sleeping bag are heaviest items so try and downgrade them if feesable.
not much of an external packer....but, internal i will say the Badlands 4500..great pack...but i personally like the Eberlestock J104 or J107. Great packs all around and if you add the duffell with the J104 or J107 you can go for days...
