I wear them preferred among the cycling jacket in Pedelecfahren to about 5 degrees Celsius ambient temperature. But the jacket is ideal: light, high water vapor transmission and good heat retention. So my lungs / chest is always nice and warm.
At the same time I can but pay still increased body heat at Bergaufpedalieren over my arms, because the jacket has no arms.
Since it rests well on the body, it does not carry on. The high collar protects me against cold wind on the neck.
