Im doing a 30-35 day hike and right now the packs im considering are a Gregory Baltoro 70, and a Arc teryx Bora 80. The bora is about 85 dollars more but it seems like it could be worth it. I need a pack with easy acess pockets for the little things and something that i can contiue to use even years after this AT hike. if anyone has any input into these two bags or has any other bag suggestions feel free to tell
