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.
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!
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 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.
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 of this pack is made with 1050d Black Ballistic to make sure the highest wear-point of the bag is well afforded against abrasion.
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.
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.
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.
We include the following accessories to give you a good amount of options for your new bag right out of the gate.
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.
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. The most popular solution is to weave the Cord Pulls through the metal pulls, effectively silencing them without having to remove them. A video demonstrating various Cord Pull options and more colors/varieties of Cord Pulls can be found on the Cord Zipper Pulls page.
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.
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 think this is a fantastic bag for all sorts of considerations. The X-PAC is great. It came with no defects and it came with a hip belt and other optional stuff like a key leash and zipper pulls.
It takes some getting used to folding it over and it doesn’t quite fold perfectly. when packed out it gets heavy and could use load lifters.
It could also use a new main carrying handle. The carrying handle is the reason I have chosen to give it only 4 stars. For a bag of this price, the handle you use to pick up from the top of the bag should be better quality, with padding so if you’re holding it for long periods you don’t feel like your hand is going to get cut up.
Honesty though I don’t regret my purchase and really think future revisions may correct that.
All around I had fun taking a trip with this bag and even found a use for the bike light attachment.
I would recommend this bag to friends because it’s fun to customize and plan. My other wish is that the pockets had more room in them or more dimension to hold a little bit more.

Great offering from the new designer. I can see heritage yet can sense a new groove emerging.
Roll-tops are fine by me. A more fluted opening width would add to the utility by way of alacrity. Peeling it back down the pack upon opening in order to access the full bag would be a tad easier. Now it's a bit snug.
Much hue and cry about exposing the X-PAC in the side pockets... I can live with that. It gives me a sense of the material. Now, it works for those particular pockets, for this use case, but don't drop Halcyon lining on other bags.
Arguably, the dimension could be deeper from your back to the outward side, I see how this might be to help keep balanced on the bike during commutes.
Something like this with more of a Smart Alec opening covered by a Shadow Guide overhanging top would be ace for me if it were a bit deeper as well.
- Tara K.Verified BuyerBought For MyselfProduct Standouts Comfortable, Durable, Good Storage Size5 months agoBought For MyselfProduct Standouts Comfortable, Durable, Good Storage SizeRated 4 out of 5 starsGreat bag, with one flaw for me
This is a big beefy spacious bag with lots of room. I have the x-pac version and I love it because it doesn’t again, can take a beating, and it’s aesthetically pleasing. My one knock on this bag is that roll top doesn’t stay rolled tight all the time. I travel with this and throw it on the plane and I have to roll it back up several times during travel to get it to stay. It’s almost like it needs a strap and clip in the middle to hold it down. Other than, I love the bag! I have several items from Tom Bihn and they just make quality lifelong items!

I thoroughly believe this bag will soon be a tight competitor with the Synik-30. The Synik and Synapse have been their flagship models for ages but the Addax is everything and more. Advantages it has over other models is it's versatility, as a pack you can just "stuff and go" and one you can neatly organize like a game of Tetris. It has the organization you want, it has the storage space you want, it has the Tom Bihn "Features" you want, and leaves not a single ounce of space un-fillable. The Addax leaves nothing to be desired. Another wonderful feature is that when I am standing on a train or bus that is crowded (which happens often as I am a frequent traveler) the Addax, even while filled to the brim, keeps close enough to my back or torso or side that it rarely inconveniences the crowd around me. Perhaps my MOST favorite part about the Addax is it's roll-top. I have read some criticism around the net regarding a want for adjustable straps but, after living with this pack a little while, I soon realized that it's actually perfect just how it is. Not having adjustable buckle straps means that when packed more fully it rounds, and means that you have less to fiddle and fuddle around with, you can just buckle and go and the need for adjusting simply falls off since when you push the buckles to meet the unadjustable buckle strap it essentially does what you would want it to do anyhow which is to "compress things" your just using your hands to compress the bag instead of a pull…

I love this bag. It has plenty of space for all my things. My only quibble is that it would be nice to have another pocket specifically for cell phone and keys. Other than that, I love this bag!
