Initially, I had bought one in black color. The fit was very good, but I had some concerns because I read comments that the shape becomes useless after a few washes. After 1-2 months and several washes, I decided to buy two more, one in blue and one in khaki. Now, after 7 months, the soles are still perfect, as for the stitching, I haven't encountered any problems, and I don't have any issues with knee sagging. At the prices I got them for, around €30, they are the best value for money. Now, for over €40, I think it's too much. If any problems arise, I will update my review!
