That's a really interesting question. I know that in the fairly recent past, a large proportion of fast riders are doing the zip-up, even the hook-up and zip right before the finish, Many were wearing mesh-top bibs. I haven't watched enough cycling TV in the last few years, since the new wicking fabrics have taken over, to know one way or the other. Anyone? Photos? Can't be within say 300m of the finish.
I just watched a little from TdF 2019. Sure was fun to watch Bernal and Alaphillipe again. I didn't see a single underlayer. Most did the 6" unzip, a very few 12" unzip. No open jerseys that I saw. Unless someone has more hot weather GT info . . .
