The Dugdale White Rose Saxony is also a good collection of similar fabrics. 15oz Tweed and has a great feel.
Very true. I wish I was one of those guys that don't tend to sweat a lot. As a Spaniard I can definately tolerate heat itself very well but I just can't stand the sweaty mess I become. The only thing you can do if you wish to wear coat and tie, it's crazy hot and you sweat like a pig is to wear the tie, yes, but carry the jacket on your arm instead of actually wearing it
