I got a Brain Bag as a gift a week or so ago, so I ordered the Brain Cell to go with it. While I was there I could not resist getting a Utility Tote, Guardian Dual Function Light (I am a light freak, couldn't resist), several different sizes of Organizer Pouches, and a sleeve for my Nook (got the one for Kindle, I hear the Nook fits). I am very excited. I had researched for months on bags, my searches always led me back to Tom Bihn. I know the other products will be the same quality as the Brain Bag, and it is something. I look forward to trying to wear these items out!!!
