EQUIPE RS JOHDAH Ultraz 3/3 Winter Jacket S11 - Men's

What Our Gearhead® Experts Are Saying:

"This is the jacket I trust when racing or training in freezing, wet conditions. The SPHERE panels and aero fit are unmatched—it keeps me protected without feeling heavy or restrictive, even on long rides. It’s the first winter jacket that feels truly race-ready."

The Assos Equipe RS JOHDAH Ultraz 3/3 Winter Jacket redefines cold-weather cycling apparel, engineered for uncompromising performance in harsh conditions. At its core, the SPHERE softshell series replaces Assos’ renowned Stratagon line, offering waterproof, windproof protection in strategically varied weights to regulate body temperature. This adaptive fabric architecture warms during steady efforts yet ramps up breathability when intensity rises, creating a balanced microclimate that keeps riders dry and comfortable across fluctuating outputs.

Supporting fabrics enhance this technical system. OSMOS thermal textiles provide supple insulation where flexibility and mobility are key, while 3-layer ZigZaggy Foam adds breathable warmth in less exposed zones. Combined, these materials deliver a jacket that blocks the elements yet feels responsive and light. The result is a second-skin fit that performs more like summer race gear than traditional winter shells.

AeroFit tailoring eliminates bulk and streamlines airflow, maintaining the aerodynamic edge competitive cyclists demand. With its blend of climate control, weatherproofing, and precision fit, the Equipe RS JOHDAH Ultraz 3/3 is more than a jacket—it’s a winter racing essential that extends peak performance into the coldest months of the year.
