I’ve used a Goruck GR1 daily for about 5 years and it still looks the same as the day I bought it. Very comfortable to wear, opens clamshell, well padded laptop compartment that still opens and is usable when the bag is stuffed, fits a surprising amount of stuff, works under airline seats. Water resistant… I bike commute in the pouring rain with it and have never had anything get damp. With careful planning I’ve been able to travel for 5 days with just that bag.
You do have to get past the GRAR AMERICA marketing, but I like having a bag that is just an unbranded anonymous black. https://www.goruck.com/gr1/
