I have one of these things in new condition:

I bought it in 2012 because it would fit a macbook pro.  It's a nice pack but my work situation shifted and I wound up using it maybe 10 times for commuting.  Since I no longer had to carry my laptop back and forth, I went back to my trusty day pack.

It's a lumbar pack like the Mountainsmith day pack, but more capacity, lots of partitions, a rolltop enclosure, and a waterproof cover tucked into its own pocket on the bottom. 

It's just sitting in a closet when it deserves to be used.  Hit me up if you want it.
