I found previous pro aero to have slightly tighter fit than climbers (the same sizes).
I can't go a size lower. I wear an S size, and the XS is too tight for my skeleton. I am 177cm, 62-64kg, and don't have any fat on me; the XS simply doesn't fit my frame. I don't have an abnormal body ratio anywhere (apart from the massively oversized nob, obviously), so this is a sizing issue with Rapha. I have seen others mention this in reviews and comments too.
The Pro Aero looked good, until I saw it in the flesh. It isn't as breathable as the Pro Climber jersey, and I really need something as light as this, due to living in a hot country which gets silly in summer.
Will check out all the other suggestions and see what they are like.
Cheers
