Assos Mille GTO Jersey S11 2026 short-sleeved cycling jersey

The MILLE GTO Jersey S11 represents the ultimate evolution of the ASSOS top-of-the-range endurance jersey. Lighter, more breathable and even more comfortable, it is designed for long rides at sustained intensity when temperatures exceed +21°C.

Its new Sens Air main fabric significantly reduces weight while improving air circulation. It has an ultra-soft feel and an enveloping fit that limits chafing, even after several hours in the saddle. The shoulders and back still incorporate Louvre Tec technology, which eliminates excess material to prevent creases and fabric build-up in the pedalling position.

The pocket system has been fully optimised for endurance: the zeroSeam construction improves stability, even when they are heavily loaded with nutrition, CO₂ cartridges or accessories. An additional zipped side pocket secures keys and personal belongings, separate from outing gear.

The regularFit GTO cut, the most comfortable in the ASSOS range, offers a stylish, streamlined silhouette that is perfectly stable both on the bike and when stationary. Strategic reflective elements provide 360° visibility, enhancing safety during low-light rides.
