MILLE GT Jersey S11 Space T

Assos MILLE GT Jersey S11 SpaceT

The MILLE GT Jersey S11 Space Trip is the lightest and most breathable MILLE GT jersey from Assos – ideal for long rides in very warm weather. The body uses the ultralight AirCell circular knit with an open hexagonal pattern that promotes air circulation and wicks moisture away quickly. Compared to the MILLE GT C2 EVO, it's around 25% lighter, while race-quality open-edge Raw-Cut Sleeves ensure a low-friction fit. The regularFit cut with set-in sleeves combines shoulder stability with excellent freedom of movement. Due to the LSF 15 on the body fabric, Assos recommends applying sunscreen underneath in intense sun; the Space Trip graphic gives the whole thing a modern, understated look, and we stock the model in 7 variants.

Technical Details and Features

At the heart of it all is AirCell, an extremely lightweight circular knit fabric with an open hexagonal pattern that optimises airflow and pulls sweat away from your skin fast. Its bi-elastic properties conform horizontally and support vertically, keeping the jersey stable even when fully loaded. The lighter Stabilizer V11 mesh at the back supports the pocket area and boosts cooling around the compartments. The three Triple Ramp pockets feature flexible 'lid' panels that secure the contents and prevent sagging when you're packing for long distances. The rear hem uses PILtec Plug-In with micro-dot silicone that grips reliably even when wet, while the open-edge Raw-Cut Sleeves eliminate transition ridges and sit aerodynamically close to the arm. Media reports confirm the combination of the AirCell body, low-friction raw-cut sleeves and stable back pockets as practical updates for endurance riding.

Use Cases and Benefits

The MILLE GT Jersey S11 Space Trip really comes into its own on hot summer rides, long base-training days and alpine climbs. The supremely airy AirCell body keeps you cool, while the sturdy Triple Ramp pockets carry food and tools securely – especially handy on full-day tours in the Alps. Thanks to regularFit, the jersey sits in a relaxed yet controlled way without flapping, and stays comfortable even in the drops. For summer layering, Assos recommends pairing it with a light Summer Skin Layer; given the LSF 15 on the body fabric, sunscreen is a smart move in strong UV conditions. If you care about clean aesthetics, the Space Trip graphic gives you a jersey that looks understated yet still turns heads.

Fit and Real-World Performance in Switzerland

The regularFit silhouette is designed for endurance comfort and suits a wide range of body types – something you'll really notice on longer rides around Lake Zurich, the Bernese Oberland or Ticino. The open-edge Raw-Cut Sleeves conform without pressure points, while the set-in sleeves stabilise the shoulder area when you're putting the power down out of the saddle. In everyday use, the grippy details win you over: the PILtec Plug-In hem keeps the jersey firmly in place even in the rain, and the Triple Ramp pockets stay structured even when loaded up. Combined with the breathable AirCell body, it all adds up to a well-rounded setup for training, commuting and long summer rides across Switzerland.
