Until Christmas of last year I never had a bag that I really liked. That all changed when I read a review of the Tom Bihn Co-Pilot by Jon Bemis on the Pen Addict blog. My particular need is to be able to carry my writing supplies to and from work so that I can journal and or write letters during my lunch break.
Fantastic post. It also gave me some ideas on what I could do with my monthly load out post.
