Our take
When a Reddit user in r/BuyItForLife calls something 'EASILY the best laptop backpack I've ever owned,' that's the kind of signal you don't ignore. This is the one to get if you want one bag that does everything.
Timbuk2 has been making tough bags for decades and the waterproof laptop line is where they shine. You're not getting the luxury feel of Aer or NOMATIC, but you're getting a bag that will outlast most of them at a fraction of the cost.
