I know you said not MiUSA but I have to shout out my favorite brand, Timbuk2. I had a Swiss Gear break on me at a bad time and went with Command laptop backpack. It’s been over a decade and it still looks like I’ve owned it for maybe 2 years, and I’m not easy on my stuff. Taken it all over the country, out of it, and always packed with tech. Almost no issues with the petty despots in the airports, and I keep it pushing.

It doesn’t look like they make the same model, but closest might be an Authority or Commuter. I can’t suggest them highly enough, and anyone I’ve know that’s bought them has felt the same.

thank goodness, I thought BP finally got ya
