PRODUCT FEATURESOur entry-level wind bibtight doesn´t compromise cold-weather performance.This is the right tight for you if you´re on a budget or if your winter riding includes only a few days of truly biting cold.Or if you want a wind tight with extra stretch. The reason this is our entry-level tight is that we swap out the GORE-TEX INFINIUM™ WINDSTOPPER® wind protection front for an Italian-made wind protection fabric with a polyester wind membrane.Some brands use this fabric on their top-of-the-line tights.Compared to the GORE-TEX fabric you give up some breathability, but on the other side you gain extra stretch.Seat pad duties are handled by our Kiss Air2 pad, which is not a huge step down from the X2 — in fact, it´s the choice of some of our pro riders. The rest of the tight is pure premium performance:the back of the legs is in our Nano Flex 3G water-repellent fabric from our top-of-the-line tights, and you also have flat-lock seams, YKK® Camlock® zippers at the ankles, and reflective strips on the lower legs. Espeficitations: AirFlex Thermo fabric on front panels for maximum stretch and total windproofness Back in Nano Flex 3G for splash resistance with maximum warmth KISS Air2 seat pad for all-day comfort Flat-lock seams Reflective Castelli logos on lower leg Camlock ankle zips with reflective zip cover.
