Assos Mille GTS Spring/Fall Bib Shorts S11

The Assos Mille GTS Spring/Fall Bib Shorts S11 are engineered for those transitional days when the line between summer and cooler weather blurs. They deliver insulation, wind resistance, and breathable comfort in a versatile package for shoulder-season riding.

These bib shorts integrate a mid-weight softshell textile with DIAMOND Ultra protection, layered to resist wind and light spray while allowing airflow. The updated S11 construction features a relaxed waist and leg opening for better comfort, increased vertical stability, and a refined aesthetic with an ultra-matte finish. The GTS S11 insert is a dual-layer 13 mm system tuned for long hours on the saddle, with perforations and goldenGate 2.0 mounting to support airflow and reduce bulk. RollBar stabilization is carried over to secure the insert under load. With a regularFit silhouette, these bibs strike a harmony between aerodynamic compression and all-day riding comfort.
