This is our warmest tight, for tough guys who don’t let a little cold keep them indoors.||Our warmest GORE-TEX INFINIUM™ WINDSTOPPER® fabric covers the entire front of the tight to keep the cold wind out. We use water-repellent Nano Flex 3G on the bum and the back of the lower legs for splash protection from wet roads, while Thermoflex on the back of the thighs gives extra stretch for the renowned Castelli fit. This is now the most comfortable wind tight we've ever made.||We’ve kept the bib straps to a minimum so that you can layer your upper body exactly as you wish, without an unwanted thermal layer covering your stomach.||With more of us riding at night, we've placed large reflective inserts on both the front and back of the legs, where the up-and-down pedaling motion grabs the attention of approaching motorists.
