The pants fit just fine. The waistband is a 3.5 cm wide rubber band that rests well without pressing on the skin. The trouser legs ends with me at about 13 cm above the knee. The waistband can be good pull over an existing paunch. The leg ends do not push. The seams do not leave bruises.
The material, 84% polyester and 16% elastane is very elastic. This fabric is quick-drying and breathable during exercise. At 40 degrees, the pants are washable and can even be dried at low heat in the dryer, but the material really dries very fast on the clothesline.
As for the compression (for better circulation and performance), I can report no special experience.
During exercise it can be stated: The fabric wicks moisture well to the outside, so that you do not happen sweaty.
Conclusion:
These sports pants, originally designed as a compression pants for sports outerwear, I wear to work and to the gym (without trousers), it simply looks good. It provides the necessary comfort, which I expect from a sports pants.
