At a time when an average cycling jersey weighed approximately 300 grams, it seemed impossible to reduce the weight of a shirt by two-thirds. However, that didn’t take account of Bio-Racer. During preparations for the Olympic Games in Athens we developed a new, super-lightweight jersey, which was worn by both the Belgian and Dutch national teams. The gain in weight – the Cool Light 100 weighed only 100 grams – was achieved by treating the textile used, Coolmax™, in a revolutionary manner with the help of nanotechnology. Micro-perforations in the front and sides resulted in extremely high air circulation. The cut was radically changed, resulting in pleasant ventilation, without the shirt catching the wind. Wearing this shirt, various national teams collected a catalogue of medals and world titles.
