I bought this boxer because I was looking for an alternative to the slightly longer pants. This boxer shorts I am very satisfied. It is breathable and wicks moisture to the outside. In one you have to look for when buying. I had the same boxer in sport in size S to. She was too small and was very uncomfortable when worn, as it has hoisted itself. The size M fits snug, but comfortable to wear, even if the legs a little pull in the direction of the step.
