I don't think anyone really answered your question, so please allow me to help.
They produce a lot of sport coats for their own brands and others, such as Ledbury, along with a very successful MTM business that they have with many local retailers and stores like epauletNY. The quality is generally very good for the money and much of their RTW is either half-canvas or unstructured. While I've switched to bespoke for my tailored clothing, I've enjoyed my pieces from L.B.M. 1911, Lubiam, and Luigi Bianchi Mantova. They've held up nicely with regular wear and care.
I still see the occasional jacket or coat that really catches my eye. It's good stuff at a fair price.
D'Avenza, Isaiah, and all the other stuff recently mentioned is, at its best, top tier. If you find a good piece at a good price, jump on it, but don't buy something you don't love just because of the name. If it looks good on you, fits well, and is decently constructed of fine cloth, it will serve you very well.
Thank you for the response. I am not only about brand, I prefer fit and function, over name. It just so happens that majority of my suits are Eidos, Isaia, and RLBL.
