I don't know if Tusting is a brand that backed out when they heard who the competition is, but I swear by my Tusting Grafton. This bag was a gift when I graduated from lawschool from my wife.
Here is a link:
Mine is the saddle leather like Joel mentioned earlier. I have never seen anyone else with this bag. The bag is lined with a heavy weight canvas. The middle slot is padded with a velcro closure to protect your laptop. As you can see from the photos on Tusting's website, its got a zipper top.
I have had this bag for 2.5 years and I use it daily. It is starting to develop a rich patina. Hopefully this will develop nicely over the next 30 years. Because it is saddle leather, it is very heavy. If you want to return it to its original look you can wash it with saddle soap.
This is a great bag.
p.s. I will post some pictures once I get my laptop back from repair. Once I can save up some money, I will be getting a duffle or two from Tusting!
