I received my first Tom Bihn bag, a Brain Bag, for Christmas. I also got the Brain Cell, Snake Charmer, and Freudian Slip. Within a couple of weeks, I ordered several of the clip-on pouches to add to it. This combination of bag and accessories is absolutely amazing! Prior to Christmas, I was carrying a separate backpack and computer case to school every day. Now I have just one bag and everything fits wonderfully! I'm tremendously impressed with the quality and love the fact that the products are made responsibly in the USA. I'll post later with a list and pictures of what I typically carry each day. Thank you for making such great products!
