The quality is very good. All cuffs are stable and still elastic, rubber pants fit perfectly and does not cut into. The fabric is very comfortable to the touch, not too thick, but not translucent thin. The stitching on the intervention are well made. The light padding on the knees do not interfere when wearing.
The color - dark blue - is discreet and unobtrusive. At 40 degrees can underpants wash very well, without discussing and without losing color.
The quality is excellent as I said, but for the wrong size specified I subtract a star.
