The Assos Mille GT Eisenherz Ultraz Winter Bib Tights S11 are designed for the most extreme winter conditions, delivering stormproof protection and comfort for long rides. The updated EISENHERZ S11 builds on the proven Ultraz line, integrating the SPHERE Ultra softshell textile from the Racing Series, known for elasticity and breathability. This material is layered over the warmest RX thermal fabric on the front, legs, and hips, creating a two-layer construction that moves fluidly with your body. Unlike traditional softshell tights, the free-floating, dual-layer design is only sewn along one edge. This reduces seams and prevents restriction while pedaling. WINTERFOAM panels provide breathable insulation around the core and lower stomach, maintaining warmth without compromising comfort. Every fabric features an eco-friendly, water-repellent treatment for rides in wet conditions.

Constructed with Assos’ AEPD 11 regularFit, the EISENHERZ S11 borrows advanced features from the Racing Series for added stability and a streamlined fit. The bodyMapping Tec design allows the thermal inner layer to move freely while the stormproof outer layer floats independently, improving flexibility. The rollBar technology stabilizes the chamois insert during dynamic movements, and raw-cut hems ensure a low-volume fit without added friction. Reflective detailing on the lower legs enhances visibility in low-light conditions, for extra safety. The Mille GT S11 Shock-Absorb Damping Mono 12 chamois provides a 12mm platform with 3D Waffle and goldenGate 2.0 technologies for breathability and friction reduction. With the added Sundeck Technology, the inserts front panel is ultrasoft and eliminates pressure. The Assos Mille GT Eisenherz Ultraz Winter Bib Tights are a must have for the coldest rides.
