Three-season usually means three seasons as they understand them in Britain or continental Europe, where May and September are not 85 degrees and brutally humid a la DC. How long do you spend out of a climate-controlled environment in your suits? Stylistically, that's an awesome suit and a great addition to your wardrobe.

The description says 11oz flannel. Is this for cold weather only or for 3 seasons? Sorry for the dumb question.
