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. ## Variants - 11.10.289.18.2XL: in stock - 11.10.289.18.3XL: in stock - 11.10.289.18.XL: out of stock - 11.10.289.18.S: in stock - 11.10.289.18.XS: in stock - 11.10.289.18.M: in stock - 11.10.289.18.L: out of stock --- Source: https://kilometro.ch/en/products/shorts-664/mille-gts-bib-shorts-s11-long-684
