Lets see how happy this backpack makes me. Just ordered my @pacmodo although at first I though the 65 dollar was an ultraslim version but it lacks a cover. So, I got the small PAC option. Although the small PAC may be too much for me :( I do hope they possibly make a "Portland Green" version just for me in the near future. :) If you are looking for a new backpack and you travel for work.
