The GT SF Bib Tights S11 introduce the new eco-sustainable POLAR fabric, which offers medium-weight thermoregulation and a soft brushed inner surface. Composed of half pre-consumer recycled fibers, POLAR marks an important step in the green journey: the fabric has been thoroughly tested to ensure that sustainability does not compromise insulation, breathability or adaptive elasticity. The external rollBar structure of the straps, adapted from the Racing series, adds a safety element to the fit of the GT S11 model, designed for endurance: an aerodynamic, stable garment designed to ensure all-day comfort. The GT S11 pad uses RS technology, integrating the MILLE insert, one of the most loved by cyclists, with a soft Sundeck panel that relieves pressure.
