I mainly bought this backback because it has a luggage loop to easily attach to a wheeled suitcase. I got sick of my old laptop bag constantly falling off my suitcase (no one wants to wear a backpack if they don't have to).

But after having this bag for a few months, it's quite clear how well thought out the design is. The padding is solid and it's quite roomy - I can fit all my laptop peripherals as well a few extra items with no trouble, and the large pouches on the side can actually fit my large 40oz water bottle, a rarity in my expericne! Easy access phone compartment is another great addition. Lots of little pouches and separators help you keep things organized. The laptop compartment has double zippers and is large and well padded. Two loops at the top give you the option of having a thick handle to carry it with or a small handle to hang it from, and of course the luggage loop so that you can attach to a suitcase handle. Clearly someone put some time into developing a backpack that's well equipped for just about any scenario.

Perfect for travel or just going to the coffee shop!
