To keep as much heat in and wind out as possible, we've used GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric, which is the warmest. We combined it with GORE-TEX INFINIUM™ WINDSTOPPER® 150 on the side panels and back of the sleeves to add extra stretch and ventilation. We tried to keep the design clean, not adding anything unnecessary, unless you consider the large reflective stripes on the chest and back pockets to be unnecessary. The jacket includes all the functional details you expect from CASTELLI, like an easy-to-use YKK® Vislon® zipper, a trio of large pockets for carrying essentials, complemented by a fourth zippered pocket for your small valuables. The new Raddoppia 3 jacket is sure to keep you warm and make you visible all winter long.
