MILLE GTO Jersey S11

ASSOS MILLE GTO Jersey S11

The ASSOS MILLE GTO Jersey S11 is your long-distance jersey for when it gets seriously warm in Switzerland and you still want maximum support. The new primary fabric Sens Air noticeably reduces weight and boosts breathability, while Louvre Tec panelling at the shoulders and back eliminates excess material and prevents bunching in the riding position. The ultralight Stabilizer V11 back panel stabilises the pockets all the way up to the shoulder area, preventing annoying sagging even when fully loaded. In practice, this means more storage thanks to seamless zeroSeam Pockets with Triple Ramp retention, plus an additional side zip pocket for valuables; add UPF 50+ protection, regularFit comfort, and a recommended use temperature of above 21 °C. The jersey is available in sizes XS to 3XL and several colourways, including blackSeries, Edge Green and Deadly Berry — currently stocked by us in up to 6 variants.

Technical Details and Features

The Sens Air primary fabric is significantly lighter and noticeably more airy than its predecessor, yet remains extremely soft against the skin and provides UPF 50+ protection on sunny days. The Stabilizer V11 back panel extends its support all the way to the shoulders, so the pockets neither sag nor swing around even when fully packed. Set-in sleeves and targeted darts at the collarbones and back, shaped by Louvre Tec, create a smooth, streamlined silhouette in the saddle. The seamless zeroSeam Pockets construction combines clean handling with the Triple Ramp pocket design, which reliably secures your contents. For on-the-go organisation, there's also a side zip pocket, and reflective Diffusor details including a centre stripe boost visibility in low-light conditions. The fabric composition is tuned for performance: main fabric 75% polyamide / 25% elastane, back panel 100% polyester; additional panels optimised for stability and stretch.

Intended Use and Benefits

Whether you're tackling Alpine passes, long base-training rides around Lake Zurich, or hot marathon days — the MILLE GTO S11 is built for endurance rides with frequent reaches for bars, gels and CO₂ cartridges. Thanks to the stable, generously sized pocket structure, you cut down on stops, stay fuelled, and benefit from a settled fit with zero pocket sag. The regularFit takes the pressure off your upper body over long hours in the saddle, while the highly breathable Sens Air minimises overheating and dries quickly when you push the pace. ASSOS rates breathability at 5/5, packability at 5/5 and drying speed at 4/5 — ideal for the variable conditions of a Swiss summer. Recommended for use at temperatures above 21 °C; pair with a lightweight base layer or a compact gilet depending on the ride. That way you get a well-balanced combination of cooling, wearing comfort and reliable storage for truly long days out.
