Love this bag. Bought this to replace my existing Swiss Army bag for work. The lined top zip pouch is key. Perfect place for sunglasses so you don't have to worry about carrying a case around. Additional small top/front pouch is great for keys, coins, and other random small stuff. Fits my computer great and plenty of pouches for anything else you need. Side pockets are big enough that your Nalgene stays put. Big fan.
