ASSOS EQUIPE RS JOHDAH Ultraz Winter Jacket S11

The JOHDAH S11’s capabilities and versatility unlock winter layering for all conditions, either as a final layer for most winter conditions or a highly breathable mid-layer beneath the SCHLOSSHUND or ALLEYCAT for winter’s worst. Every textile is oriented for on-bike effectiveness, shielding exposed areas and your body’s leading edge while increasing breathability where protection is less necessary. The biggest change for the S11 generation is the new DIAMOND Medium softshell, deployed across the jacket’s front and upper sleeves. More elastic, more protective, and more breathable than the previous generation’s SPHERE textile, DIAMOND improves aerodynamics while reducing overall restriction – a second-skin fit without pressure. The jacket’s sleeves are constructed with ZigZaggy foam for muscle-wrapping, stormproof protection, and OSMOS Heavy on the back panel maintains thermoregulating warmth while maximizing breathability in less exposed areas. The built-in gilet returns, but with a different textile. The new LITHIUM Medium is an insulating layer with a grid construction that promotes extreme breathability. During hard efforts or long climbs, unzip the DIAMOND shell to ventilate, and the LITHIUM gilet maintains a warm layer across the chest, modulating temperature without complete exposure to the cold. Even when the jacket is completely zipped, the integrated Diffusor valves constantly work to actively regulate internal temperature, preventing overheating in variable conditions.
