Here's what other sites are saying:
Daily commutes just got easier with the Gregory Sector Backpack. No, double espressos and bacon-maple bars don't appear magically every day, but you will have more functional options than with your old bag. Plus, that's better for your waistline anyway. Switch it up with either a left or right shoulder carry, so one side doesn't become over-burdened, and get to your goods by the U-shaped main access or the side-load configuration. Easy. Options.
