UMA GT EISENHERZ Ultraz Winter Bib Tights S11 - Women's

What Our Gearhead® Experts Are Saying:

"The EISENHERZ S11 bib tights have been a game changer for my winter rides. The SPHERE Ultra fabric keeps the cold at bay without making my legs feel stiff, and the RX thermal fabric underneath provides just the right amount of warmth. Plus, the two-layer design reduces seams, so the tights move effortlessly with me throughout every ride."

The Assos UMA GT EISENHERZ Ultraz Winter Bib Tights S11 bring a new level of comfort and performance to cold-weather cycling. Building on the proven Ultraz line, these tights feature the SPHERE Ultra softshell, a stormproof textile originally used in Assos’s Racing Series. This fabric offers a more elastic and streamlined fit, increasing breathability while shielding us from wind, rain, and cold. The unique two-layer construction, with the softshell layered over a warm RX thermal fabric, ensures a cozy ride even in extreme conditions.

The EISENHERZ S11’s innovative design goes a step further by reducing seams—only sewing the layers together along one edge—allowing for a greater range of motion. This means the tights move naturally with each pedal stroke, avoiding the stiffness that often plagues traditional softshell bibs. With thermoregulating, breathable, and water-repellent properties, the RX thermal fabric maintains warmth while letting excess heat escape, ensuring we stay dry and comfortable on every ride. From long winter rides to chilly commutes, these tights are crafted to handle the toughest elements without sacrificing performance.
