UYN Racefast cycling bib shorts

After being the first to develop a bib short with a hybrid structure that combines the properties of knitted fabric and Lycra, the UYN Racefast bib short was born, an entirely new innovative product. Initially, we focused on the design and fit, as we wanted the Racefast bib short to follow movement without constricting while staying in the right position. We achieved this goal through the high elasticity of the knit, a structure with a reduced number of seams, and the strategic use of Lycra in the seat area. Additionally, we introduced a new system of flat elastic straps and developed a perfectly anatomical pad to ensure unparalleled seating comfort. To produce the most advanced bib short, we developed new ventilation systems based on pedal dynamics. With the exclusive Dynamic Ventcuff system, we transformed the traditional cuff into an advanced air intake. Thanks to the VorTex-3D technology, the airflow envelops the quadriceps, dissipates excess heat, and regulates the temperature on the skin's surface. Your legs are always ready to unleash new power.
