Description

The Assos Equipe RS Johdah Ultraz Winter Jacket S11 Black Series is the ultimate winter jacket for the avid cyclist.

With the new DIAMOND softshell, you enjoy maximum protection, breathability, and freedom of movement.

The Assos Equipe RS Johdah Ultraz Winter Jacket S11 in Black Series sets a new standard in high-performance winter clothing. This 2025 edition is designed for riders who don't want to compromise between warmth, protection, and aerodynamics. The iconic JOHDAH jacket has been completely redesigned with a two-layer DIAMOND softshell, which offers superior elasticity, breathability, and protection compared to previous generations.

Unique to this jacket is the integrated INTRABOOSTER vest, a thermal shield that provides extra warmth to the torso without compromising freedom of movement or ventilation. Combined with the racingFit fit, the jacket fits like a second skin and moves effortlessly with every pedal stroke.

To prevent overheating during intense efforts, the signature "diffusers" on the shoulders have been reintroduced. These draw in fresh air, keeping your body temperature stable even during long climbs or fast descents.

Whether you're training in freezing temperatures or touring in harsh conditions, this jacket offers the perfect balance of warmth, protection, and performance. Lightweight, streamlined, and designed down to the smallest detail to help you get through the toughest winter miles.
