After going through way too many backpacks that just end up falling apart, I bit the bullet and bought an Aer City Pack Pro and I couldn't be happier. It's rugged, durable, and most importantly: it stands upright on its own!!! Every other pack I've had just falls right over when setting it down. I also love that I can walk through pouring rain and none of my stuff gets wet.
That sounds perfect and there is nothing that lasts longer than Cordura fabric. My 20 year old Brenthaven business case with should strap still looks brand new but it’s killing my shoulder. The Day Pack 2 looks like it would fit my 15” laptop, etc nicely. Thanks for the rec.
