Overall, I really like this bag; for me 4 stars means it does everything I want, 5 stars means it absolutely blows me away. And for what I want to use this bag for, putting it under the seat while most of my stuff is in the overhead, it does a fantastic job (including being large enough to hold a full sized iPad). My main issue is that the organization is a little weird; the two front pockets are structured in a way that a lot of stuff doesn't fit into them very easily, and it would be easy for things to get lost in there. But that may just be a peril of having a bag that's mostly tall, and I love that it has a secure, separate water bottle section (my 25oz Owala pokes out, but it's held in very securely). I'll be curious if they iterate on the design, but as it stands it is very good at what it does.

Just used the Co-Pilot on a 2 week trip to Japan and it worked out great for me. I especially liked this format for airplane seating. It's big enough to fit the key gear but small enough footprint to keep on the floor. I also used a new Synik 30. I have a Synapse 19 which doesn't sit well on the floor hence the Co-Pilot. The 30 was either checked or tucked into the overhead storage.

Packed a ton of stuff including a 13" MacBook Air M3. The center zip housed a 27oz/800ml Klean Kanteen. I used a flip top straw cap.

I used it for souvenirs, snacks, maps, sunscreen, hats, note pads, cards, pens, and the like.

Use it again? Yes.

Any issues? No.

Complaints: Only minor - with the shoulder strap that twists around in the pad.

I use this along with my Technonaut 30 to have the perfect setup for 2-3 day work trips. I pack all of my clothes, toiletries, shoes, jackets, whatever in the backpack, and the co-pilot works as my matching "briefcase". I can store the bigger backpack in the overhead compartment, and the co-pilot can stay in the seat with me and hold my laptop, water bottle, headphones, and a few pens/snacks/medicines.

It's such a small and simple thing, but I can't believe how much I love the placement of the water bottle pouch on this bag. It keeps it "centered" so nothing feels unbalanced, and it's upright to avoid spills. Plus it zips away to keep things looking professional. Can't say enough good things about this bag.

If I am going on a longer worktrip I'll sometimes empty this out and pack it flat in a larger rollaboard suitcase that I check. Then when I get to my destination I can take it out and use it as a bag to carry things when I adventure out into the city.
