TLDR
If you need a large backpack for everyday carry, the Brain Bag is the one for you. You'll be blown away by not only its size, but also its utility, versatility, and longevity.
Full Description
The Brain Bag debuted in 1996 and its design has stood the test of time. The ultimate on-your-back student or business organizer, the Brain Bag is our Slant-6 of backpacks: it will surprise you with its utility, versatility, and longevity. Long after lesser bags have frayed their seams, blown their zippers, and popped their straps, the Brain Bag will continue to be your faithful companion.
Two Main Compartments
In both of the main compartments (on the back panel of each) are two unobtrusive webbing loops (that we call "rail loops") to which you can secure the optional Cache. Many of us will appreciate this functionality on a daily basis: the rail system can be a convenient and quick way to remove one's laptop from the bag.
Three External Pockets
On the front of the Brain Bag are four external pockets. The small top pocket is perfect for a wallet and cell phone and has an inside snaphooks for keys. The two vertical pockets are large enough for water bottles or even a small thermos; inside both of these pockets are pen/pencil organizers. The left pocket has an outside flat mesh pocket for brochures, plane tickets, or even a small U-lock bike lock. Between the pockets are two lash straps for an umbrella or a raincoat, and above these straps is a heavy-duty snaphook so you can attach a water bottle, coffee mug, or what-have-you.
Side Compression Straps
Side compression straps compress the Brain Bag when it is not full and stabilize the load; you can also tuck a raincoat, hoodie, or yoga mat under these straps.
Breathable Back Panel
The back is made of Spacer mesh and is padded with 3/8", high quality, closed-cell foam. This combination of mesh and smooth nylon is designed to provide maximum breathability while still being gentle on your clothing.
Edgeless Shoulder Straps
Conformity is overrated — except, perhaps, when it comes to shoulder straps. The edgelessness of the Brain Bag shoulder straps allows them to more softly conform to your shoulder — we find that this increases comfort. Yet the straps aren't too soft: the 1/2" thick EVAZOTE® OEKO-TEX® certified foam means the strap is robust enough to carry a heavy load.
What's Included?
1x 8-inch Black Webbing Snaphook/Snaphook Key Strap
A Key Strap is a strip of webbing with plastic snaphooks on the end. The 8” Key Strap in Black that’s included in most of our larger bags is, for many, the gateway to a world of organization via Key Straps and Organizer Pouches. All the members of the Key Strap family are intended to make locating things in your bag easier and more instinctive. Pulling out a small item or pouch tethered to a strap is easier than rooting around aimlessly in the depths of your pack; you can also rest assured that anything hooked to a strap is much less likely to fall out or otherwise be left behind. You can find more Key Strap colors and varieties on the Key Strap page.
A Set of Black Zipper Pulls
Some folks prefer metal zipper pulls. Others prefer cord pulls. So, what to do about that? We think the best solution (in most cases) is to offer metal pulls and include a starter pack of Cord Pulls with most bags.
An adjustable and removable sternum strap with leave-no-trace hardware: if you don't like or don't use your sternum strap, remove it and leave (almost) nothing behind.
A simple webbing waist strap that can offer extra stability when running to catch a bus, plane, or train. It can also add a small measure of support for a heavy load (for a truly supportive hip belt experience, please see the optional 1.5" Padded Hip Belt.) Also features leave-no-trace hardware.
What's Optional?
The 1.5" Padded Hip Belt allows you to carry some of the weight of a loaded pack on your hips rather than just your shoulders.
Want to carry one (or two!) laptops? Get the Cache sized for your device and use the loops at the top of each main compartment to attach your Cache when you need it and remove it when you don't.

My 12 yo needed a bag upgrade and he absolutely loves the brain bag. Has pockets for everything he needs, and love the toughness of the ballistic nylon.

I looked for years to find a sturdy and reliable bag that was well made and would last through my travels. This backpack is extraordinary. Everything I have been looking for!
So far I have taken to Spain, Morroco and Mexico in some harsh environments and it is perfect. The zippers are high quality and the material is excellent. I couldn't be happier and I will be buying another smaller one for short trips.

Best bag I have ever owned. Durable and comfortable even with heavy loads. Love the material and zipper quality. Easy to stay organized while working on the road in Western Canada.

Picked up the brain bag as my partner has run through several backpacks for carting his stuff to and from work over the years and has very picky requirements for a replacement. The Brain Bag checked off all these requirements easily with it's reinforced top handle, hip belt and sternum strap in addition to the large functional pockets. I got one for myself as well and was a little worried about the size because I am quite short (5'1") and the bag is quite tall. However, it hasn't been an issue due to the compression straps. Being able to cinch it down when it's not full is a game changer!
I only wish the brain bag version of the Freudian slip and the 1.5 inch padded hip belts were currently available/in stock because I think adding these will make it the perfect backpack.

Great bag. Been using my super ego for 10 years. Decided I wanted to switch over to a backpack and it’s been a joy. I’m also really happy the cache I bought with the super ego (the biggest one at the time) fits wonderfully too! This is my third bag from Tom Bihn. My lineup now includes the super ego, the medium cafe bag and now the brain bag. Thank you!
