I was able to check out the Yalta London Transport bag out at Interbike and was very impressed. It is the perfect size to carry your daily needs, and it looks incredibly stylish. The grey tweed definitely evokes a British vibe, and I also like the way the laptop slides into the bag. It looks like a very convenient system. I am hoping to be able to to review this bag in the near future, and will bring you more details as I discover them. Below is text from the Chrome press release.
LONDON TRANSPORT
Introducing the London Transport Citizen & Yalta, inspired by the land of tweed, punk and pilsner. The Chrome City Series is our take on the unique materials, graphic treatments and methods that define the culture and lifestyle of a selected city. The LT Citizen and Yalta are made with bomb-proof coated technical tweed that references the look of the 19th century with the performance of today. The inside liner features a custom Victorian-inspired print by Brooklyn-based Flavor Paper and the leather front panel on the Citizen is embossed with our iconic logo.
