Looking forward to seeing what you come up with, Fred
For now I’m using this small Hikpro pack that I got on Amazon for less than $20. It does the job, is the perfect size (I can fit my Macbook Air, keyboard/trackpad, Roost stand, chargers and spare batteries, as well as a light down jacket or rain jacket) and takes up almost no space if I pack it away. It also works well as a “personal item” on flights, so I can have easy access to some stuff throughout a flight and I can gate check the Tortuga if I feel like it (I fly quite often on small Dash-8 400Qs).
What I do not like about the Hikpro is that it looks fairly “cheap”. I’m not sure that is something that’s easy to fix while keeping it lightweight, but just removing the awful logo would help. If you guys can make the Tortuga daypack not look out of place in an office setting, I would consider switching!
