The fabric is soft and very breathable with moisture-wicking properties so important for women having hormonal fluctuations.

I chose a small size as the closest to my measurements. The pants fit OK but are big on the waist and small on the thigh. The proportions could be better if the waist was smaller or had a drawstring or the top of the leg was slightly more generous. I could not go up a size because the waist would fall down.
Note: the review question on sizing is impossible to answer as too big and too small, hence 'true to size' chosen as the average of the two!
