<p>The invention relates to a fabric of per se pliant material for aerodynamic equipment and devices, such as clothing for speed sports, including: skating, cycling and athletics, which fabric is at least partially provided with a pattern of recesses. This fabric thus displays a certain roughness, which in particular embodiments is even macroscopic, which results in a substantial effective decrease in the drag which can substantially increase the speed attainable with a given wind-force, muscular strength or muscular power, or can markedly reduce the energy required to attain suc h a speed.</p> |
