I don't know if anyone's given the winter ones a go (not that I need any more winter outer layers). It's sort of tempting to get another pair of bibs/summer jersey in advance. The pad and fit of my summer bibs are so far beyond anything else I have (sportful, Rapha, dhb).
25% off everything at lapassione.cc with SPOIL25. I can't vouch for their jerseys, but their bibs are amazing and amazing value.
