## Assos EQUIPE RS JOHDAH ULTRAZ Winter Jacket S11

The Assos EQUIPE RS JOHDAH ULTRAZ Winter Jacket S11 is the performance-oriented winter jacket for road cyclists who want to ride fast even in truly nasty weather. It was developed for **high-intensity rides** in harsh winter conditions and combines protection, warmth, breathability and freedom of movement in a surprisingly slim package. At its heart is the new **DIAMOND Medium** softshell from the S11 generation, which is noticeably more elastic, protective and breathable than the previous SPHERE material. This makes the jacket feel like a **second skin** and remains aerodynamically unobtrusive even at speed.

- **DIAMOND Medium** softshell on the front panel and upper arms for storm-proof, breathable weather protection
- Integrated **intraBooster** vest made from **LITHIUM Medium** with grid structure for additional insulation without heat build-up
- Active ventilation via **valveTec Diffusor** shoulder vents that regulate temperature even under load
- Sleeve construction with **ZigZaggy** 3-layer textile; back panel made from **OSMOS Heavy** for thermo-regulated warmth
- **zeroSeam Pockets** with **STABILIZER V11** for splash-resistant, stable pocket contents
- **AEPD 11 racingFit** with WorldTour feedback for 360° stability and compressive, aerodynamic fit
- Developed in the Assos **Textile Laboratory Lugano** (Of Switzerland)
- Available in **blackSeries** colour, in six sizes from XS to 2XL

## Technical Details and Features

The new **DIAMOND Medium** softshell forms an independent, storm-proof barrier while being temperature-regulating – it improves aerodynamics and reduces restrictions compared to the previous generation. The sleeves feature **ZigZaggy**, while the back panel made from **OSMOS Heavy** specifically stores heat and maximises breathability in less exposed zones. The integrated **intraBooster** vest made from **LITHIUM Medium** creates an additional, highly breathable insulation layer; this allows you to open the outer layer for more airflow without completely exposing your torso to the wind. Even when the jacket remains closed, the **valveTec Diffusor** vents on the shoulders actively work against overheating and keep the microclimate dry. The **AEPD 11 racingFit** wraps the body with 360° stability; **zeroSeam Pockets** and **STABILIZER V11** secure contents and minimise splash water – the jacket is available in **blackSeries** finish and in sizes XS–2XL.

## Applications and Benefits

The JOHDAH ULTRAZ S11 is aimed at ambitious riders who are out in Swiss winters between cold, bise winds and changeable conditions. As an outer layer, it performs excellently on most winter days and impresses with its **second skin** fit and efficient climate regulation during intervals, long base rides and fast group rides. When conditions get really rough, the jacket can be used as a **highly breathable midlayer** under **SCHLOSSHUND** or **ALLEYCAT** – the system thinking makes the set-up flexible. The combination of active ventilation and integrated vest allows fine temperature control without constantly fiddling with the zip. Independent tests of the S11 line confirm the effectiveness of **valveTec Diffusor** and the new material platform; **DIAMOND Medium** is explicitly assigned to the JOHDAH Ultraz line.

## Fit, Sizes and Construction

Assos uses the **AEPD 11 racingFit** for the JOHDAH ULTRAZ S11, which fits like a glove in riding position and combines aerodynamics with stability. The material coordination follows **body mapping**: exposed zones are more heavily shielded, less exposed areas remain maximally breathable. Developed and refined in the Assos **Textile Laboratory Lugano**, key materials like **DIAMOND Medium** and **LITHIUM Medium** come from in-house textile research. The jacket is available in **blackSeries** colour and in six sizes from XS to 2XL, allowing ambitious road cyclists to find the right fit. Assos also emphasises the storm-proof, wind and waterproof performance of the new softshell platform without building unnecessary bulk.
