I bought this pack quite recently from Joe and the gang at ZPacks. It's meant for around town and day hikes. I would feel bad returning it since it's particularly customized, so I'm selling it here. It's a nice pack in my opinion, I just like the other day/around-town pack I have more.

Anyway here are the specs:

Size: Medium with pack height shortened + 20" torso height (I'm 5'11" and usually go with 21" for the torso but find a smaller torso height sometimes fits better for using the pack around town)
Color: Army Green
Material: Hybrid cuben
Features:
- Center mesh pocket
- Roll top closure + taped water tight so your stuff won't get drenched
- hydration port
- extra-wide interior water sleeve so that it can also fit a laptop
- foam taped in the bottom to prevent damage to fragile objects when putting the bag down (you can remove this if you want)
- If you want to add a hip belt, water-bottle pockets, or any other features I'm sure you can send the the pack to ZPacks and they'll add them for you (for a charge).

And finally, price: $150 shipped conus
