Equipe RS JOHDAH Ultraz Winter Bib Tights S11 - Men's

What Our Gearhead® Experts Are Saying:

"I’ve ridden plenty of winter bibs, but the JOHDAH Ultraz S11 is on another level. The DIAMOND fabrics create a real storm barrier without feeling bulky, and the new compression fit is supportive but comfortable all ride long. Add in the Waterskin ankle cuffs and the updated RS insert, and it’s basically my full winter solution in one piece."

When the coldest days threaten to keep us indoors, the Assos Equipe RS JOHDAH Ultraz Winter Bib Tights S11 prove that winter riding can still feel fast, comfortable, and protected. Assos developed an entirely new family of DIAMOND stormproof softshells for this generation, giving us a tighter-knit defense against icy winds, freezing road spray, and unpredictable winter skies. The twinDeck system layers DIAMOND Ultra over OSMOS Light in the front for maximum insulation and breathability, while DIAMOND Medium across the lower back balances warmth with storm protection.

The paneling is mapped with precision: OSMOS Heavy behind the legs improves airflow where we need release, and Waterskin ankle sheaths lock out cold spray and drafts from every angle. The S11 cut eliminates unnecessary seams, wrapping the muscles in 360-degree compression while reducing pressure points for a frictionless, second-skin feel. Stabilized by the X-Frame bib system, the fit remains secure even through all-out efforts.

At the core is the RS S11 insert, a racing platform with shock-absorb damping foam, 3D Waffle perforated structure, and kraterCooler ventilation that keeps our microclimate dry. This combination eliminates the chill that comes from moisture buildup, ensuring comfort on rides that stretch deep into winter. Whether we’re logging endurance miles or sharpening with intensity, the JOHDAH Ultraz S11 bib tights are our go-to for staying warm, dry, and race-ready all season long.
