For road cyclists who spend extended time in the saddle and won't compromise on chamois depth, the Assos Mille GTO Bib Shorts S11 are men's road bib shorts built around a 21mm dual-layer chamois that sits deeper than the inserts in the GT and GTS variants. OSSIDIA leg panels (80% polyamide/20% elastane) deliver muscle-compressive support with a friction-free surface, while LOSANGA front inserts (78% polyamide/22% elastane) provide ultra-breathable stretch in the panel most likely to restrict breathing under sustained effort.
The GTO S11 Insert chamois uses a Shock-Absorbing Damping System Twin construction, separating the impact absorption layer from the surface contact layer to reduce pressure accumulation on long climbs and rough road surfaces. Made with OEKO-TEX certified and PFAS-free textiles and rated for use above +21 degrees Celsius, the 21mm Shock-Absorbing Damping System Twin chamois and OSSIDIA leg panels place the Mille GTO Bib Shorts S11 at the top of the Assos men's Mille bib line.
