MILLE GT LS JERSEY S11

Assos MILLE GT LS Jersey S11

The MILLE GT LS Jersey S11 from Assos is a long-sleeve racing jersey for hot, sunny days when breathability and UV protection are equally important. The long sleeves provide UPF 50+ protection, while the extremely airy body is designed for maximum cooling. Due to the very lightweight body material with UPF 15, Assos recommends using additional sun protection on the skin during intense sun exposure. Thanks to regularFit, the jersey sits comfortably and securely without restricting freedom of movement on long rides in Switzerland; available in multiple colour variants so it matches your setup visually.

• Ultra-lightweight body made from AirCell for maximum breathability and cooling
• Long Push Pull sleeves with UPF 50+ and aerodynamic silhouette
• Back pockets with Triple Ramp Pockets and Stabilizer V11 carrier material
• Raw-Cut Sleeves without edges for clean transitions
• PILtec Plug-In with micro silicone dots on the rear hem for secure hold even when wet

Technical Details and Features

The body consists of AirCell, an ultra-lightweight circular knit with an open hexagon pattern that promotes air exchange, quickly wicks away sweat and supports cooling. The Bi-Stretch properties provide horizontal body-hugging fit and vertical support, so the jersey maintains its shape even with loaded pockets. The Push Pull sleeves wrap around the muscles elastically, stay very thin and deliver UPF 50+. Assos also uses Raw-Cut Sleeves for smooth finishes without annoying seams and the proven PILtec Plug-In, whose micro-dotted silicone hem stabilises the back area – even when it gets damp. The back is supported by Stabilizer V11, a particularly airy mesh fabric that securely holds the Triple Ramp Pockets.

Applications and Benefits

This long-sleeve summer jersey shows its strengths on long rides with strong sun exposure – whether commuting in the city, on rolling Mittelland loops or on high alpine passes. The combination of UPF 50+ on the arms and super-airy body offers protection without creating the typical "oven pipe feeling" on hot days. For Summer 1/3 Layering, it can be ideally combined with a light Skin Layer underneath; this keeps the climate stable even with changing altitudes. Because the body is very thin (UPF 15), additional sun protection is recommended on exposed areas.

Fit, Materials and Variants

The cut is a sleek regularFit that allows plenty of freedom of movement while still offering flutter-free stability on long distances. Set-in sleeves improve arm freedom and stabilise the shoulder panels, which is particularly noticeable when climbing out of the saddle or on long ascents. Depending on the colour variant, the material composition varies: the BlackSeries variant features a mix of polyamide, polyester and elastane, while other colours use a higher polyester content. Regardless of the blend, the function remains identical: maximum breathability, quick drying and reliable hold.

Pocket and Carrier System in Detail

The three back pockets are constructed with Triple Ramp Pockets: elastic "lids" secure your contents, while the lower, more supportive zone prevents sagging. This makes it easier to access energy bars, gels or your compact wind vest without anything falling out. The jersey also uses the Stabilizer V11 back panel, which in the current S11 generation from Assos is known for its combination of cooling and stability; technical tests praise the pocket stability and clever panel layout in the S11 programme. Together with the PILtec Plug-In hem, the load stays calm even on rough surfaces – practical on Swiss back roads and gravel connectors.

Care and Practical Tips

For a long lifespan, we recommend washing the jersey promptly after sweaty rides on a gentle cycle and avoiding fabric softener so the fine structures of AirCell and Push Pull remain elastic. On very sunny days, a light Sun-Skin-Layer or sunscreen under the body is worthwhile to supplement the low UPF there. Combined with lightweight bib shorts and breathable socks, this creates a summer setup that remains comfortable even during heat waves. Those starting in the early morning hours should pack an additional wind vest in their pocket – the Triple Ramp Pockets keep it securely within reach.
