In reply to blue_sundown: Been looking for similar and found the Patagonia Nano Puff vest was a very nice fit. I'm 5'10", slim build and that was a size Small.
The Rab Strata? Vest is also an option and thanks to the stretch side panels it is fairly easy to alter the side seams to get a perfect fit. (Saw one last month another climber had done this to.)
Don't know about the others.
