The Assos Mille GT Eisenherz Ultraz Winter Bib Tights S11 offer a streamlined regularFit performance for the harshest winter conditions. Borrowing a softshell from the Racing Series, these bib tights enhance breathability and introduce a free-floating, two-layer design that delivers total winter protection without compromising on flexibility. The stormproof SPHERE Ultra softshell, first introduced in the Racing Series, offers a more elastic, streamlined fit with improved breathability over previous models. This softshell is layered over the S11&';s thermal body fabric on the front, legs, and hips, with the unique two-layer construction connected along only one edge to minimize seams and maximize movement. Unlike typical softshell bib tights, the Eisenherz S11 provides freedom of movement with every pedal stroke. The tights&'; core is made of Assos&'; warmest RX thermal fabric-thermoregulating, breathable, and water-repellent for enduring winter comfort.
