Windproof MILLE GT Wind Jacket S11 packs ultralight protection with quiet stability
What Our Gearhead® Experts Are Saying:
“This jacket hits the sweet spot for packable protection. Breaker fabric handles wind extremely well, and the elastic side panels prevent that stiff, parachute feeling you get with some shells. The fit stays stable and silent, and it breathes well enough for tempo efforts without overheating.”
Designed for cyclists who demand windproof protection without excess bulk, the MILLE GT Wind Jacket S11 brings together ultralight materials and precision paneling for efficient, year-round layering. Breaker fabric forms a supple, protective barrier against gusts and light precipitation, delivering stability on exposed descents and cool-weather rides.
Sens Super Light inserts along the sides and sleeves introduce multidirectional stretch and airflow, allowing the jacket to contour the body while preventing heat buildup during high-output efforts. The rustle-free engineering eliminates distraction, maintaining a quiet, streamlined profile even at speed.
Packable enough to carry on every ride yet protective enough for rapidly changing conditions, the MILLE GT Wind Jacket S11 excels as a versatile layer for endurance training, shoulder-season miles, and long routes where weather and terrain shift hour by hour.

Frequently Asked Questions
How packable and light is the Assos Mille GT Wind Jacket S11 for fast group rides and races?
The Assos Mille GT Wind Jacket S11 weighs just 78 g (size M) and self-stows into its chest pocket with a zipper and clip-tab/karabiner, fitting in your palm so it disappears into a jersey pocket without adding noticeable bulk.What is the fit of the Assos Mille GT Wind Jacket S11 and how should I size it with a base layer?
The Assos Mille GT Wind Jacket S11 has a race-fit BodyMap patterning—close-to-body with pre-shaped elbows and a curved rear hem—so size it based on the base layer (regular for standard jerseys, go up a size for chunkier layers); for example, a 100 cm chest equates to size M.Can the Assos Mille GT Wind Jacket S11 handle light rain and how durable is the fabric?
The Mille GT Wind Jacket S11 is showerproof with a PFC-free DWR and a PU membrane bonded to 100% Pa ripstop (47 g/m²) for water resistance and tear durability; it also uses an Aquaguard-coated YKK Vislon zipper, but it’s not a fully waterproof shell for prolonged heavy rain.For what temperatures and riding scenarios is the Assos Mille GT Wind Jacket S11 best suited?
Assos positions the Mille GT Wind Jacket S11 for roughly 8–18°C (46–64°F), making it ideal for cool mornings, windy rides, and three/four-season training or racing when you need minimal bulk, aero efficiency, and quick stowability—riders report it reliably extends the season by 1–2 months.
