I lived out of this pack from Aarn packs for 6 months on my AT hike. I put tried to keep heavy stuff in there to balance my load, I stood more upright than others. Everything I needed until getting to camp went in these: snacks, water, weed, and camera. Everybody gets a trail name, mine was 'titty pockets'.

I highly recommended these packs, not cheap but worth it.
