NIce quality, comfortable fabric, dries quick, and retains color after multiple washings. However; the fit did not work 100% for me. The legs kind of rode up and the boy shorts had a tendency to ride down, especially with consistent bending up and down activity. Good product but not a perfect fit for my shape. The bikini style was ideal and purchased multiple times.

Very comfortable, right length

Size: Large, Color: Black,grey

This product arrived as described. I like the trunk length, not the boxer brief length. They are comfortable. Hold up well when worn and washed. I don't seem to sweat as much. These were ordered to replace ones ordered about 2-3 years ago due loss of weight, had to down size. The waist band doesn't roll as like other brands.
