TLDR
The Addax 31 is a roll-top bag with room to spare! Two options for water-bottle carry, spacious device pockets, and a cavernous main compartment mean if you need to carry it, the Addax 31 can help you reach that mountaintop.
A few highlights of its features:
- Carries a nominal capacity of 31 liters with 3 rolls and a maximum capacity of 48 liters when fully unrolled.
- Tons of pockets and organization: 5 exterior pockets, 5 interior organizational pockets, and a total of 9 o-rings throughout
- Plenty of quality-of-life features: luggage pass-through, substantial suspended laptop pocket with zippered quick-access, exterior water bottle pocket, integrated strap keepers
- Fully lined so you can easily see the bottom
If really big is too big and you want something with the same features but a little smaller, check out the Addax 26.
Full Description
The Addax 31 is more than just your classic roll-top pack. It has the thoughtful design that you'd expect from us, so let's dig in and get into the nitty-gritty!
Roll-Top
It's what makes the bag what it is. The roll-top is secured in place by two 1" side-release buckles, a male on one side and female on the other. The idea behind this is that you can either clip them to the clips above the shoulder straps or to each other if you want easier access but a less secure attachment versus a more secure attachment but more complex access (after all, who doesn't want secure attachment?)
At 3 rolls we've measured the bag out at 31 liters -- we call it the Addax 31 because this is going to be the way most folks carry the pack day-to-day. One roll to secure the load is measured at 41 liters; no rolls right up to the stitch we measured at 48 liters.
The Front
The front pockets are a generous size to help you keep the things you need access to quickly close-at-hand. The top has two equally-sized pockets to keep the smaller bits corralled and the bottom is a nice-sized open space perfect for your headphones.
Both have two o-rings in for your organizational needs.
Right at the bottom of the front is an attachment point perfect for things like a back light for safely riding at night (the roll-top is a style beloved by bicyclists in particular, after all!) A little cheeky swatch of color lines the back of the grab point, a secret splash of color for you.
The Sides
On one side there is a gasp exterior water bottle pocket. We know that we've, to put it gently, steered-away from exterior water bottle pockets in the past but, well, folks keep asking for them! It's OK to stand on principle sometimes but easy access to water is something I think we can all agree with.
The other side is good-sized pocket for keeping items that are a bit larger or longer but still need to be handy.
The Bottom
The bottom of this pack is made with 1050d Black Ballistic to make sure the highest wear-point of the bag is well afforded against abrasion.
The Back
Poring over the back panel of the Addax reveals a luggage passthrough for those times when your ungulate must fly. Hidden in this pocket is a seat for the optional frame sheet, little sewn corners to hold it in place should you choose to use it. The back panel has closed-cell foam under spacer mesh to keep your back cool. The bottom has some black pack-cloth to add a little extra strength at a rub-point.
The shoulder straps are our wonderful 1/2" EVAZOTE® EV50 Edgeless shoulder straps, cushy as always, with built-in strap keepers to help keep the danglies at bay. Finally, a fully-removable sternum strap and gate-keeper waist strap appoint this pack in the usual TOM BIHN style.
Device Pockets
A rather large laptop pocket (16.5" x 10") made from our spacer mesh with an exterior zip as well as interior access, much like the one in our Synik 30 but a bit larger! Inside the main pocket, sewn to the laptop pocket, there is a tablet pocket that is almost as big (12" x 9.5") for even your bigger tablets.
The Inside
So now to the inside of the pack. It's cavernous. A quick-tip for packing in and packing out is to flip the roll top over at the bottom seam for easier access to the goods inside when doing your pack and unpack. Along with the tablet pocket mentioned in the Device Pockets section, there are two webbing pockets sized the same as the pockets you'll find in the top-front zip pocket, for the little items you want packed away a little tighter.
As with all our bags, we just threw o-rings at it and saw what stuck. 4 o-rings are positioned along the front-side of the main pocket to help you pull out what you want quickly without needing to dig through your bag in its entirety.
What's Included
We include the following accessories to give you a good amount of options for your new bag right out of the gate.
One 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 Addax can hold a lot! Although the padded back panel provides a lot of built-in support and if you're schlepping around a laptop that's also going to be plenty rigid, if you want something to add some stiffness to the back panel or if you want to use the Padded Hip Belt to take some of the weight off your shoulders, the Internal Frame is a good idea.
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.

I got the Addax as a multi-purpose travel bag and couldn’t be happier. I’ve used it twice for different reasons. The first as just an easy weekend getaway bag. It was perfect in this regard as it allowed me to do one bag travel and easily fit under an airplane seat. The other as a convention carry along that I could store goods in while having it secure on my back while walking. Perfect in this application too. Could not recommend it enough.

I really like it. It fits my needs perfectly for commute and travel. Even short hike are quite comfortable. The quality is excellent and it looks like a very durable bag with very good materials. The bag is very comfortable for a non-hiking bag. Love it

Love the flexibility that the roll top provides. This thing holds a ton!! Amazing quality and I love the thoughtful little details throughout. I bought the x-pac version and it gives the bag just enough rigidity to stand when packing.
This was my first Tom Bihn purchase and it likely won’t be my last!
