I'd feel I'm not doing you a service by not mentioning the GoRuck GR1. Fits all your needs and is a great pack, but you'd do well with about anything on this list.

My GoRuck has been around for close to 10 years and on deployments, used for college, my main carry on. I've shot off it, thrown it off trucks. If anything ever goes wrong with it, they'll fix it no questions asked.
