I searched for a good looking and well-designed back-pack style bag for a LONG time. I encountered PKG in a boutique, and looked them up online, and found the Concord. 1) It is one of the best looking backpacks I've ever seen. The light grey is just perfect -- forgiving with dust/dirt, but not anonymous black. Also very important to me: NO (super prominent) LOGOS!!! 2) The material is durable and water resistant (doesn't darken in the rain or take stains from sloshing coffee). 3) The design is very good. It combines comfortable supports for the back, that keep you cool, smart pocket designs, and enough space in the main compartment. The removable insert is more useful than I would have expected -- it's great for school/office paperwork and books. The top handle lets you carry it with one arm, as opposed to on the back, if you like. 4) The laptop compartment is just right for my machine, and leaves plenty of room for other stuff.
I use the bag every day at university. I get lots of compliments on it.
Lastly, you can't beat PKG customer service. I needed the bag 'all of a sudden', and they were able to deliver incredible expedited service.
Tobin, thanks so much for your detailed feedback! Glad you're happy with the bag. If you have any questions or concerns in future, please feel free to let us know.
