Assos - MILLE GTS 2/3 Bib Shorts S11 - Men's - Black Series

The Assos Mille GTS 2/3 Bib Shorts S11 represent the next evolution in premium endurance Assos bibshorts, delivering amazing wind protection and advanced thermoregulation. Designed by Assos of Switzerland, these Assos bike shorts strive to be the perfect balance between long distance comfort and aerodynamic performance. 

The new S11 update introduces DIAMOND Ultra softshell technology - the lightest and most breathable fabric in the DIAMOND family! Offering waterproof protection, rapid drying and a second-skin like fit. This textile projects another new addition: the return of Assos' kukuPenthouse technology, offering ultrasoft, ultrabreathable providing support to the male genitalia. This new construction adds ultrasoft fabrics that maximises comfort and warmth across the core.

The beloved butterfly-wrap panelling returns  for the S11, enveloping your muscles in micro-adjusted compression whilst accommodating aggressive riding positions that aim to achieve peak aerodynamics, ensuring these Assos bibs perform across training miles and race efforts alike.

The updated S11 insert radically increases cooling airflow, with the dual-layer construction adding 4mm of targeted support to the 9mm base of microshock-absorbing foam.
