First purchased this item in a medium (per waist measurement). Nice fit. Then ordered a small (per Speedo sizing). Nicer fit. Quality of construction is first rate. Material is translucent and stretchy. The elastic is not binding, doing the job as intended. The pouch is great! You are not pulled down as with most supporters and there is plenty of room unless you are "horse hung". They do ride low but there is no "plumber's crack" and you don't (unconsciously) keep tugging them up. Plan to buy another pair: The price is more than I usually pay for underwear, however, I will treat myself! Only wish they came in more than white or black color wise.
