The BlackHawk Advanced Tactical Briefcase works great and I highly recommend it. There are many functional pockets with plenty of admin organization; the two main compartments for a laptop and notebooks are waterproof. Everything secures well and is combfortable to wear even when hauling heavy loads. The briefcase blends in well at the office and is rugged enough for the field (although I have never had to bring a briefcase to the field). The Blackhawk logo is dead-center of the breifcase, so you might need to "adjust" that if it seems too noticible. I have the Coyote Brown and it is significantly darker than in the stock photos from Blackhawk, which is a good thing. All their pictures tend to be very light.
Pros: Comfortable, Functional, Durable
Cons: None
