MILLE GTS Bib Shorts S11 Long

Assos MILLE GTS Bib Shorts S11 Long

The Assos MILLE GTS Bib Shorts S11 Long are designed for long distances and bring aerodynamics, compression and comfort into a balanced form. The S11 generation has been constructed with less restriction at the waist and leg cuffs, while a new suspension system increases the vertical stability of the chamois. An ultra-matte finish and additional cooling airflow over the two-layer insert emphasize the focus on long distances and warm weather. Two leg lengths are available, with the Long variant covering the thighs +3 cm further – ideal for riders in Switzerland who rack up lots of elevation gain.

• rollBar suspension from the Racing Series S9 for stable chamois positioning
• Volkano textile with UPF 50+, high abrasion resistance and silky-smooth compression
• PILtec Plug-In leg cuffs with micro-dot silicone for secure hold, even when wet
• zeroPressure Waist for supportive, pressure-free waist comfort
• GTS S11 Insert with 13 mm Shock-Absorb Damping System Twin, 3D Waffle, kraterCooler, whirlKrater, goldenGate 2.0 and kukuPenthouse front panel
• Available in XS–3XL and in two lengths: Standard and Long (+3 cm)

Technical Details and Features

The main material consists of 80% polyamide and 20% elastane; the chamois insert contains 85% polyester and 15% elastane, providing durable recovery forces and rapid moisture transport. The exclusive Volkano knit offers abrasion resistance, UPF 50+ and a rich, matte appearance on the outside, while supporting with silky-smooth compression on the inside; Mineral Tec integrated into the yarns provides lasting odor control. The S11 construction uses Butterfly-Wrap-Paneling that evenly wraps the muscles and reduces micro-fatigue, combined with the regularFit of the GTS line for aerodynamic fit without racing stress. The rollBar fixes the insert during weight shifts, the PILtec Plug-In grippers stabilize the leg cuffs, and the zeroPressure Waist distributes tension comfortably around the abdominal and lumbar area. The revised GTS S11 Insert increases airflow and combines a 9mm base with additional 4mm zones for a total of 13mm damping; 3D Waffle, kraterCooler and whirlKrater optimize ventilation and drying, while goldenGate 2.0 improves lateral mobility and the kukuPenthouse panel reduces pressure at the front.

Applications and Benefits

These bib shorts show their strengths on long base training rides, alpine passes and summer commuting, where cooling and stability are equally important. Tests emphasize the very good performance in heat – outdoors as well as on the trainer – thanks to breathable construction and efficient chamois ventilation, which noticeably improves skin climate and seating comfort during long sessions. The Long leg length offers additional protection and a calm silhouette on the thigh, which is particularly pleasant during changing positions when climbing out of the saddle and on descents. Together with the moderate compression level of the GTS line, this creates a convincing package for ambitious long distances in Switzerland, without demanding the tight racing character of the Equipe series.

Fit, Sizes and Combinations

The MILLE GTS S11 falls into the regularFit category and is aimed at riders who prefer a streamlined but not ultra-tight fit. Thanks to sizes XS–3XL and the choice between Standard and Long, leg coverage can be individually adapted to stature and intended use. For a harmonious setup, the manufacturer recommends combining with the MILLE GTS Jersey S11 as well as lightweight Summer 1/3 GT or Endurance layering systems – ideal for long days between the Mittelland and the Alps. Those who appreciate maximum stability at the chamois will noticeably benefit from the rollBar layout, which keeps the insert in position even during sprints, ramps and cornering.
