The ASSOS Dyora RS Winter Bib Tight S9 is an aerodynamic, full-length tight built with water and windproof fabrics to ensure we stay warm and dry during our winter training rides. It combines SPHERE Ultra and SPHERE Medium fabrics with OSMOS Heavy insulation for optimal cold-weather protection, all without sacrificing breathability. Its S9 raceFIT construction features A-Lock Engineering framework to ensure stability of the insert as we pedal, while the rollBar bib straps and ergoBox work together to minimize uncomfortable friction.
