For real winter it's not really enough and I had to wear something over it at 8 ° C for the first km. After a few kilometers it was okay with only a slight, thin undershirt.
At +11 ° C with thin undershirt, elbow pads, and backpack Löffler Active Shell Vario (summer rain jacket without sleeves) I turn very difficult to end the ride up a sweat. (Sporty driving style, 9 km)
The material is left feeling. Not like at a much expensive "winter" -Trikot, but also on me, it makes a good impression. Also I find the processing well and the zipper is smooth. He is not just of allerbilligster quality, but as for me something that's bothering him making waves. At least if one is prevented something.
Reflective elements are in place at the sleeves and back, but I would like to see more. Especially with cycling clothing which is intended for the cold, dark time.
I am 178 cm tall and have ordered directly in L due to another review. That was just as well, because at the sleeves M would me Been too short.
Price / performance fit with this jersey. I ordered a second and my for biking in the winter purchased Sweatshirts then probably remain better in the closet.
These two jerseys will be good service to me until spring / summer. ;)
