The Sorpasso Wind Tight reaches the zenith of the Sorpasso tight and knicker range. They have the same build and construction as the standard Sorpasso full length tight, except they feature Gore Windstopper X-Fast membrane textile in addition to the Thermoflex Duo core in the thigh and knee panel. This added wind proofing helps drop the temperature range to 25°-50°. These amazing tights now extend the range well below freezing, however, will not cook you when the mecury rises. The Sorpasso Wind Tights receive Castelli's Rosso Corsa designation which means it is a top tier Castelli product and receives their best stitching, best pad insert and finest anatomically cut materials.
The Sorpasso's front leg panels are constructed of Gore's Windstopper X-Fast 2 married to Castelli's Thermoflex Core Due. This unbeatble pairng is the ultimate for keeping your thighs and knees protected from the elements. Thermoflex Core Due is a core Castelli cold weather textile and for good reason. It provides both windproofing, wet weather barrier and warmth/moisture control through hollow core fibers. The back and uppers use standard Thermoflex where supreme weather protection is not required. Thermoflex in all of its forms is super elastic, so when cut and stitched in anatomical patterns, Castelli can achieve a tailored-like fit. In addition to fit, Thermoflex also provides excellent muscle compression. The flat, thin and elastic suspenders are the familiar Giro++ design that provide support, while staying low profile. The bottoms of the tights are finished off with the elastic Giro3 bands and 10cm YKK zippers.
Since the Sorpasso is a Rosso Corsa product, it receives Castelli's best insert, the Progetto X2. This insert is designed to disappear beneath the rider. It has two distinct components. A skin care layer that is bacteriostatic, soft, elastic, seamless and is designed to prevent chafing. The other feature is the cushioning layer that features variable thickness with extra viscous padding beneath the sit bones and perineum. Castelli has always had a knack for getting the chamois fit and profile just right and their inserts are seeked out by riders worldwide. The Progetto X2 is no exception and is their best offering to date.
