<!--ProdInc[300315641]/Mall:[backcountry_US]-->Riders who enjoy a bit of crisp weather on the lower legs or dont like the feel of an ankle zipper will enjoy Castellis Sorpasso RoS Knicker, which confidently braces against winter elements that would typically drive you to months on the indoor trainer. Designed for slightly warmer conditions that the Sorpoasso RoS Bib Tight, the Knicker still receives Castellis familiar NanoFlex technology, now in its third generation, to boost water repellency while maintaining the breathability and warmth weve come to expect. As youre bent forward in the riding position, the anatomically mapped 3G paneling provides ample stretch to allow unrestricted movement at the knee and hip. Under heavy clouds and paceline wheel-spray, the Knicker sheds water with relative ease. Nano Flex Xtra Dry fabric is sewn to the upper bib, thighs, and the rear of the legs, so youll stay dry and maintain body heat to maximize winter performance. <h3>Details</h3> Go-to training knicker for winter base miles Third generation NanoFlex sheds water and keep you warm Anatomically designed paneling for compression and stretch Lie-flat bib straps conform to the riding position Leg panel end at calf-belly Castelli revolutionizes inclement weather riding gear Item #CSTZ7DW <h3>Tech Specs</h3> Season : Nano Flex 3G, [upper front/thighs] Nano Flex Xtra Dry Fit : form-fitting Chamois : Progetto X2 Air Claimed Weight : [large] 10oz Manufacturer Warranty : 1 year
