Assos EQUIPE RS JOHDAH Ultraz Winter Jacket
Assos has taken the best and made it even better, ensuring the Assos EQUIPE RS JOHDAH Ultraz Jacket delivers even more freedom of movement, more breathability, and more all-weather protection, all built into an advanced body-mapped design that adapts seamlessly to your every move. Whether you're training in sub-zero conditions or chasing watts through snow-dusted climbs, the new JOHDAH ensures winter is no longer a barrier to peak performance.
At the heart of its innovation is the all-new two-layer DIAMOND softshell, replacing the previous generation's SPHERE fabric with enhanced stretch, airflow, and weather defence. Paired with the integrated IntraBooster gilet, it provides powerful core warmth without the bulk. Iconic Dual Diffusor valves at the shoulders inject cool air between layers to regulate body temperature, preventing overheating even during high-intensity efforts. For elite cyclists who ride more outdoors than inside during winter, the EQUIPE RS JOHDAH delivers unmatched technical performance for comfort in the harshest conditions.

About Assos
Swiss precision. Half a century of obsession.
Assos of Switzerland was founded in 1976 by Toni Maier-Moussa with a single ambition: reinvent cycling apparel from the inside out. The Lycra cycling short, modern bibs, the chamois as we know it — all began here. Half a century later, the obsession with precision and ride feel hasn't moved an inch.
Assos still designs and engineers every piece in Switzerland. The brand operates its own laboratory, its own development pool of test riders, and its own assembly line for the most demanding garments in the range.
