It’s designed to keep your stuff organized in compartments and it does. It's also designed to allow the user to pack or unpack in less than 10 seconds. I never move that quickly so I'll take their word on that.
The hanger hooks make it versatile if you wish to hang your gear or just get it out of your backpack. If you have clothes that are wrinkle resistant, even better.
I found the PackGear to be a great addition and will give it the true test when I take a longer trip this spring. Thus far, the only down side I’ve found is that the fasteners can be a little stiff. I’m sure they’ll loosen up over time with use.
Another pro, it comes with a 30-day money back guarantee.
