I once compiled a list of all the attributes I wanted in a backpack. For the last 5+ years, the Boundary Supply Errant X-PAC has been my bag. I’ve tried many, many others during that time, but kept going back to my Errant because it checked the most boxes. I’ve finally found a bag that can replace it.
Here’s my list:
1. Somewhere between 20-25L, no smaller or no bigger. This is the Goldilocks size IMO, where it holds everything I need for EDC or travel, but also small enough and comfortable to wear daily and for long periods of time. And it fits under an airline seat. Both bags check this box, but I like that the OneGo 2 is not quite as tall as the Errant, but a bit deeper. While the Errant has a slightly slimmer profile, the lack of depth makes it more difficult to fit certain things.
2. Comfortable straps and rear mesh panel, preferably with a sternum strap. Both bags have good padding, but I always found the Errant straps and foam a bit too rigid. The OneGo 2 padding is more cushy and feels a tad more comfortable.
3. Padded laptop compartment that can fit an iPad Pro 13 M4 with Magic Keyboard and Apple Pencil. Ideally, this is a separate compartment and easily accessible. They both do this well, but I prefer the magnetic closure on the OneGo 2 because it doesn’t require me to unbuckle a fidlock. The soft padding enclosing the magnets is a nice touch as well.
4. Modularity or the ability to fit separate cases within the bag, ideally a clamshell design. Both do this well.
5. Preferably a separate top and bottom, divided by some sort of partition (extra points if that partition is moveable or removable). The Errant did not have this, and it was always one of my biggest gripes. The OneGo 2 absolutely NAILS this.
6. Easy/quick access to the top part of the bag. Both do this well, but I prefer the OneGo 2 because I don’t need to pull down on the flap to unlatch it, and it’s one magnet vs two. Where the Errant is better is the added zipper for added security.
7. Easy/quick access to the bottom of the bag (this usually means side access, but some bags execute the rear clamshell opening really well). The OneGo 2 has both side access (on one side) and a clamshell. The Errant just has the clamshell.
8. Structure so the bag has the same general shape whether it’s full or empty. Some bags are really floppy and soft without anything in it, while others have a nice frame or more rigid exterior. One of my biggest complaints about the Errant, it’s floppy without anything in it. The OneGo 2 has a nice rigid frame/structure, whether it’s empty or full.
9. Stands up on its own. The Errant sort of does this when packed a certain way, but the OneGo 2 stands up no matter what.
10. Quick access pocket on the exterior, preferably felt-lined. The Errant has one nywool pocket on the front, the OneGo 2 has a side quick access pocket with a bit more organization. I’d say they’re tied here.
11. Separate zippered compartment for portable charger, pen/pencil, key fob, AirPods. They both satisfy this, but a bit differently. The Errant had a dedicated side pocket that fit a large portable charger, pen, detachable key ring and AirTag. The OneGo 2 I had to put all of these things in separate places, but all easily accessible.
12. Key loop. Preferably a detachable one. Errant wins on this one with its magnetic detachable key ring.
13. Side pocket for water bottle, tripod, etc. Errant has one, OneGo 2 has two. They both won’t fit a large bottle.
14. Luggage pass thru, so bag is in vertical position. The Errant has a strap that you have to fasten to do this. The OneGo 2 has a side handle that doubles as a luggage pass thru. I prefer the vertical orientation, so I wish the OneGo 2 had a horizontal strap on the back.
15. Hidden zippered pocket on back. Errant has this. The OneGo 2 does not, but you can put a passport wallet in the side pocket and lock the zipper.
16. Solid top handle and a side handle (extra points for grab handle on the bottom). Both have top and side handles, but the OneGo 2’s handles are better (bigger and more robust).
17. Magnets > Velcro (Velcro is loud and wears over time). The Errant has more magnets, but arguably too many. The OneGo 2 has just the right amount.
I’m absolutely thrilled with this bag. There are only a couple things I would add/change.
1) Some way to secure the top magnetic flap when needed. It’s fairly easy to open from behind.
2) A horizontal luggage pass thru strap on the rear panel.
3) Expandable side pockets to fit larger water bottles (like Wandrd does with a zipper or Nomatic with the magnets)
4) The sternum strap could be a bit wider/thicker (it seems a bit thin).
