Knightsbridge is a very good manufacturers of these traditonellen Harrington jackets. The upper material seems "more stable" than other manufacturers and, most important, the lining in the sleeves is the same plaid lining as in the other parts of the jacket and so much more pleasant. Processing total also very good. For size, I can say that the size designations but adequate, if you want to wear sporty little tight, such as boxers or so :-)
