This is my first time posting here and have a question about these packs and your experience.

My son and I current have Teton Explore 4000 and Teton Scout 3400 backpacks. These have served us well so far as beginner backpacks and have taken them on 3 - 5 day backpacking trips.

However we are preparing for Philmont next year doing a 12 day backpacking trip, and would like to upgrade these. My son will be 16 by then, probably around 5' 8", I'm 6' 1".

I was thinking about buying Osprey Volt 75 for myself, and Osprey Volt 60 for my son. However, someone just pointed me to the Osprey Aether AG 70 as well. The only real benefit I see to that is the day pack, is that really worth the extra ~$80? I already have a pretty nice Osprey Daylight Day pack.

Just curious on your thoughts. I see the Volt 75 for ~$150 on amazon and the Aether AG 70 for ~$232 on Amazon.
