Assos Equipe RS Johdah Ultraz Winter Bib Tights S11

Push harder through winter’s extremes with the Assos Equipe RS Johdah Ultraz Winter Bib Tights S11, engineered for high-intensity efforts in cold, wet, and variable conditions.

These elite bib tights bring together Assos’s all-new DIAMOND series stormproof softshells with precision mapping to protect where you need it while maximizing breathability elsewhere. The front features DIAMOND Ultra in a twinDeck over OSMOS Light construction to block wind and moisture while preserving stretch. The lower back uses DIAMOND Medium for splash protection, and rear leg panels utilize OSMOS Heavy for ventilated coverage. Ankle areas are wrapped in Waterskin for waterproof, windproof sealing. The ergonomic S11 cut maintains a second-skin aerodynamic silhouette, supported by the RS S11 insert. That insert features a 9 mm Shock-Absorb Damping System Mono platform, 3D Waffle perforations, and kraterCooler ventilation to keep your microclimate dry and performance alive.
