Knack Medium Expandable Backpack
GearKnack Bags are the ultimate multi-use backpacks and have become our new go-to for everything from daily use and quick overnight trips. The genius behind these backpacks is the combination their expandable chambers and actually useful and well-thought-out pouches, pockets, and sections. The medium size seems to be the most like a regular sized backpack and the most versatile in our opinion. No need to bring a separate bag for the gym when heading into work. Just pack it all, including your laptop. We also found that at the fully expanded setting, we were able to fit a few changes of clothes and an extra pair of shoes for our weekend trip with the guys.
