The characteristic feature of the shorts is that they are composed of an inside layer (1) made of an impregnated material with apertures (4) on the surface, which in the lower part of the legs is connected with the outside layer (6) made of an elastic material, where the legs of the inside layer (1) have zippers (5) or some other type of elastic fastening on the inside. In the apertures (4) of the inside layer (1) there are penetrators (8) which have the shape and arrangement of two coaxial rolls; a smaller one (a) and a larger one (b) with bevelled edges and rims (9) in its lower part.
