bought 4 pair in different colors. They look great and fit well and have some room with the elastic waist. Very, very satisfied. Will buy more next summer for sure.

Comfy shorts with plenty of leg room.
Size: 46, Color: 01khaki
These shorts run huge, in the legs. Nice material, well made, waist was the right size, but too much in the legs.
