I'm looking for a backpack that's generally capable of carrying 35+ pounds (upwards of 50), but isn't actually heavy (frame, etc), pseudo-UL, or UL. I prefer internal frames. Right now, I'm torn between Granite Gear Blaze A.C. 60, and Osprey EXOS 46. I'm getting it for a long section hike, but could see myself living out of it depending on how long my hikes become down the road (hence my desire for storage). Storage, weight, and comfort are the most important to me. Are there any packs you can recommend that would accommodate me in this regard, or are one of the packs I'm looking at exactly what I need?
