Assos - MILLE GT Shell Jacket S11 - Men's - Black Series

The MILLE GT Shell Jacket S11 is a versatile, stormproof layer built for year-round adaptability. Engineered with a new windproof, water-repellent textile and improved breathability, it's the ultimate outer shell for unpredictable weather. Designed to layer effortlessly over summer jerseys or heavier winter jackets, it ensures complete protection from wind, rain and road spray without sacrificing comfort or mobility. 

Whether you're facing sudden summer storms, tackling cool shoulder-season rides, or adding a final defence against winter's worst, the S11 Shell provides the three essentials - windproofing, waterproofing and breathability in a streamlined, easy-to-pack design. Its extended collar and hem offer enhanced coverage, while ultra-elastic cuffs create a secure seal with or without gloves.
