In the TdeF, why did the yellow jersey holder, and sometimes white, polka cut off the jersey's collar?

I’ve been puzzling over this one. No pro goes to the extra effort without a reason. Who knows?

Ideas:

Comfort, did the collar rub the neck the wrong way?
Heat, was it cooler?
Aero, was it more aero?
Another reason?

They didn’t seem to do this to their team/trade jerseys so I’m left wondering.

I do have some off the shelf jerseys that could be more comfortable, cooler or more aero (the collar might prevent the jersey from conforming to the shoulders). Is doing away with the collar helpful?

Thank you in advance if you are in the know and will let us know.

It looks like it’s just for comfort. I only looked at Egan. It looks like he is simply trying to get that jersey close to the Castelli jersey he wears.

From memory, Alaphillipe who was in the yellow jersey most of the time did it the most. I don’t think he did it on his first day; yet, after that I noticed and wondered what was up.

I don’t think anyone cut the collars off their jerseys. I think there’s just a lighter-weight version of the jerseys that don’t have a collar.

Agreed. I think the key thing to notice is that on the lower cut yellow jerseys, they still retain the “LCL” logos that are now around the collar bone are instead of on the collar.

You could be right and I’m wrong. Did see some pictures of a short collar compared to the large collar at the podium.

This site had the closest image of what I was remembering and it still looks cut to me. Maybe not.

The yellow jersey they get on the podium is just an ornamental trophy. They would never ride in it. It has full length sleeves and zips in the rear.
