I believe this is the “FreeX” fabric (very quick drying and lightweight) Top- Size S Bottoms- M Drawstring ankle cuffs Only flaw is a small hole in the right side pocket (my pen poked through when I was in a hurry to get in the car on the way to work). Hardly noticeable, easily repaired. Flaw reflected in price Would prefer to sell as a set Smoke and pet free home
