Taken size M, thinking he had a 38-40 but a 40-42 (and this is mentioned in the description of the sizes after checking!) Very light, soft and very flexible, dries quickly (not yet adapted to the current outdoor climate ;-) here, already tested indoors. Perfect and useful side pockets (sometimes difficult to find a woman slacks fluid has 2 real pockets). Thank you to the other assessments that have allowed me to make a choice easier among several models of the same style. Low waist but not too much, just like in the photo. There is no elastic waist, you choose the clamping link, so perfect even if it's a little big, soft hand provides a very good fell and it still allows better movement. Taken to play tennis among other ... and the white is not too transparent. Very nice, really, to recommend, I'll probably take a 2nd shortly.
