A garment for a part of the body, and in particular a sport pant, includes an elasticity element, or a number of such elements, disposed on a portion of the garment, while another portion of the garment is free of elasticity elements. As a result, the garment can store energy by elastic elongation under a movement of, for example, a leg. This energy can then be released under a second movement of the leg in the opposite direction, resulting in the garment supporting the second movement of the leg.
