    Great 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!

    Perfect fit

    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.

    A great opinionated bag

    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.

    An EPIC new addition to the TB line-up and my new all-time FAVE!!!

    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…

    Cool design and materials

    I wanted the Synic 30xpac, but there is always a supply issue. Ended up w the addax. Cool idea and materials. It doesn't tighten down as much as I would have expected. It would be nice if there were more compartments, outside and especially inside.
