I’ve used vented laminated Klim up to 42c, although once you’re in the 30’s you’re better off with mesh and I may well buy one to take with me on my next European jaunt.
Since laminated doesn’t get saturated like a layered jacket would, they dry quickly. One often overlooked factor is that, in the UK you’re often dealing with rain one minute, sun the next, rain again etc. I don’t want to have to stop and change kit every time the weather changes, let alone squeeze into waterproofs while getting wet or have to fit a liner in my jacket only to remove it half an hour later because I’m overheating. The Klim is the closest thing I’ve found to a jacket that handles it all - wet, dry, monsoon, and all four seasons.
