Description

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. 

The Brain Bag consists of two main compartments plus four external pockets. The small top pocket on the front is perfect for a wallet and cell phone and has an inside snaphook for keys. The two vertical front 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 water bottle, coffee mug, or what-have-you.

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 (available in sizes specifically for every Apple laptop and iPad. When you add the Cache, the Brain Bag becomes a "checkpoint-friendly" laptop backpack. Here's how it works: on the back (or bottom, depending how you look at it) of the Cache are two parallel "rails" of 1" wide lightweight nylon webbing which extend from the top to the bottom. Included (and already attached for your convenience) when the Cache is ordered with the Brain Bag are two Gatekeeper Rail Clips: unclip the side that isn't clipped to the Cache, slip it through the webbing loops in the Brain Bag middle compartment, and flip it shut. Slip the Cache inside the Brain Bag, and pull it back out: you'll see that the Gatekeeper Rail Clips ride the rails of the Cache, allowing you to remove your laptop from the Brain Bag entirely while it is still encased in the protective Cache. Doing this at the airport security checkpoint means the X-ray machines (and TSA personnel) will have a clear, unobstructed view of your laptop — allowing you to keep your laptop in the Cache and the whole affair securely held together as one unit. (We think that's much better than having to remove your laptop and dump it in one of those buckets.) Many of us will appreciate this functionality on a daily basis as well: the rail system can be a convenient and quick way to remove one's laptop from the bag.

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. The Brain Bag has a top handle made of 1/2" PORON® foam wrapped in 1050 denier ballistic nylon fabric. And what about the 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. Removable 3/4" sternum strap and 1-1/2" waist straps are there if you need them but are easy to remove if you don't. The back is made of Spacer mesh and is padded with 3/8", high quality, closed-cell foam.

If the organizer pockets on the front of the Brain Bag just aren't sufficient, or if you need to carry papers, folders, etc. and keep them neat, consider adding the Freudian Slip. One side will protect those papers; the other provides extra organization for pens, business cards, and small electronics or laptop accessories.

Best computer backpack ever

I don't even remember exactly when I bought my Brain Bag, but gotta be more than 10 years ago. I take it nearly everywhere, 50% of the time with two computers, 30% of the time with two computers plus an iPad. And power adapter, and trackball, and cables, and... Usually it is *very* heavy, making its lack of failure quite impressive. Have dropped it more than occasionally on account of the taking it nearly everywhere; zero damage to contents. I keep expecting to need to replace it, but so far only one thing failed, after years of heavy use: One sternum strap broke. Easily, quickly, and cheaply replaced.

I thrive with my Brain Bag!

I purchased my Brain Bag in 2016. I regularly travel over 100,000 miles a year (outside of the pandemic), and have my Brain Bag with me almost everywhere I go. It safely and comfortably carries all of the technology I need for work and then some. I've also used it to travel to rural and mountainous areas in India and many other countries, and on more than one occasion, used it for a comfortable pillow. My Brain Bag let's me carry everything I need to thrive anywhere! It's the last working bag I'll ever need. Highly, highly recommended!

Well, certainly the best backpack on planet earth.

I bought my Brain Bag like 20 years ago and have taken it to work everyday and on every trip I have taken since. All the zippers and seams are like new, and for a serious traveler, reliability is much more important than price. Buy this backpack. It is worth it to have one possession that is absolutely perfect and always will be.

The BEST Laptop Bag

I bought my Brain Bag in 2012. Amazingly, it still looks and functions like new. The ballistic material has survived leaking water bottles, exploding pens, the occasional weekend hike, and heavy abuse from lugging around a 15" MacBookPro plus books and A/V equipment every day. The bag is large, but it's comfortable to wear. I love the padded straps and padded top handle. My only complaint is that Tom Bihn no longer makes the excellent Brain Cell to go with this bag. Thanks to this backpack and the Brain Cell, my laptops have never had a scratch on them, despite literally dropping the backpack on the floor, checking it on a plane, etc. Thank you for making such a great product!

Best backpack *ever*

I bought this bag on the recommendation of a friend during a trip to the US. I've been using this bag for the past 16 years, and it still looks like new. The zippers all work fine, there are no rips or tears, and with the exception of a single buckle that I broke while closing it in a car door (that I have since replaced), this backpack functions like the day that I bought it. I cannot recommend this backpack enough. I would be more than happy to purchase another one of these bags, but I highly doubt that this one will wear out before I retire (easily another 16 years). This bag is awesome to travel to conferences with, as you can use the backpack for all your stuff, but still pull out the smaller laptop bag for meetings and the like. I consider this bag "buy it for life".
