Hydration Reservoir
What kind of hiking backpack should i get?

Some friends and I are going on a 3-4 Day Hiking trip in the Appalachian mountains, and I need to buy a good backpack for it. My price range is about $150. I don’t really wanna go over that by very much. I want a backpack that has an Internal Frame, and also that is going to fit me properly (Im 6 foot 9 inches and not very wide). Obviously im gunna need to be able to carry my Sleeping Bag and tent along with about 3 days worth of food. Im not too worried about its capacity though, because im a very efficient packer. Also I have a CamelBak Hydration Backpack, and I’ve heard that some Hiking Backpacks are made to be compatible with Hydration Packs (I assume that just means there’s a place for you to put the reservoir in the hiking Back Pack), so I’d like for it to be Hydration Pack compatible. As i know very little about hiking backpacks, any tips on what kinds would properly fit my needs would be much appriciated
