Best Pack on the market!!
I bought my Brain Bag in 1998 and have carried it all over the world along with daily use. I originally purchased it to carry all my paramedic books. I then carried it daily in an ambulance where it was heavily abused. It then carried me through nursing school and in 2012 it carried me through 4 years of nurse practitioner school. I carry it daily to and from the hospital. Its contents change frequently but its durability has stood the test of time. It is faded and somewhat worn but not a single hole and all the zippers are original. Amazing product!!! It has carried me through 28 years of life and continues to do so.

The Black Hole Bag I'd been Waiting for
This bag is BIG. I'd been looking for something that could hold all my essentials for the day, including a bulky sweater, a packed lunch, laptop, and a change of shoes for my walk to work, and wow does this fit the bill. I love the ability to cinch the bag down when I don't need all the volume. One of my favorite features is the little mesh pocket which is so convenient for my work ID, as well as the carrier straps between the two front pockets which I've used for both an umbrella and a tripod. I'd love to see this exact bag but a little bit shorter, for a person with a smaller frame. Magnificent bag as is and I would buy it again.

Love it - so much versatile space!
Outgrown my Empire Builder after 10+ years and needed more space for packed lunches, IT kit and general EDC stationary like folios and pens as I don’t have any workplace storage and work hybrid. The Brain Bag is absolutely perfect for this and I have space to spare. Love it!
