Abstract: A garment with localized compression effect for performing a sport, the garment being obtained by assembling first pieces of basic elasticity and second pieces that present a compression effect. The garment includes a plurality of types of second piece suitable for producing different compression effects, each type acting in a determined compression range; each second piece is arranged so as to produce a compression effect that is either longitudinal or transverse; and the second pieces of the various types are arranged in the assembly so as to surround certain transverse sections of at least one limb and/or the torso in full or in part and so as to exert a non-uniform compression effect with a pressure gradient that decreases towards the heart. In a variant, the second pieces are selected from three types, having compression ranges that correspond to compression effects that are respectively weak, medium, and strong.
