The Assos MILLE GTS Spring Fall Bib Shorts S11 redefine transitional-season performance with a new generation of insulation and protection. Engineered for endurance, they combine midweight thermal comfort with advanced wind and water resistance for unpredictable spring and fall conditions. The hallmark innovation is the DIAMOND Ultra softshell, the lightest material in Assos’ new DIAMOND family, delivering unprecedented breathability, waterproofing, and stretch for a true second-skin fit. Beneath it lies the return of kukuPenthouse technology, offering an ultrasoft, ultrabreathable cradle for the male anatomy to enhance comfort and microclimate regulation. The butterfly-wrap paneling stabilizes and supports the muscles through fatigue-reducing compression while optimizing aerodynamics in aggressive riding positions—an ideal blend for long, performance-driven rides.

Internally, the GTS S11 introduces an updated insert featuring dual-layer construction: a 9mm base of microshock foam topped with 4mm of targeted cushioning to improve endurance and comfort over extended distances. Enhanced airflow channels dramatically increase cooling efficiency, while expanded coverage around the waist and lower back boosts thermoregulation and core support. Complementing the softshell exterior, OSMOS Light provides adaptive insulation that actively manages temperature to prevent overheating while maintaining gentle compressive support to promote blood flow. Designed for cool, damp, or variable conditions, the MILLE GTS Spring Fall Bib Shorts S11 pair seamlessly with the MILLE GT Spring Fall Jersey C2 or GTS Jacket S11—and for more extreme weather, can be layered with additional ASSOSOIRES for professional-level adaptability.
