First of all, I have washed the Funktionslauf- shirt because it smelled a little chemically. It is dried quickly on a leash and the smell is completely gone. It fits like a glove and is very pleasant on the skin. It spans not, is light and elastic. It has an optimum length to even warm the kidney and still ensure excellent freedom of movement. I welcome that the zipper is held by a small particulates up from the skin of the chin away, I do not like it that is when the neck or chin picks something or scrubs. Also, the collar is a tight squeeze, but it does not constrict, you hardly notice it. Despite that it protects the neck a little against wind and weather, and the thumb holes at the end of the arms, are very good, so cool hands in the transitional period do not get too out of.
Overall a very well thought-out long-sleeved running shirt, in a nice color.
