"A crucial element of cycling in winter, a long-sleeved ASSOS skinFoil cycling base layer is designed to be the ultimate first layer underneath your ASSOS bib tights and bonka jacket for the coldest months of the year. As the heaviest of our skinFoil collection, this breathable base layer for winter riding benefits from a specific blend of moisture-wicking yarn and a long-sleeved design that renders it more than capable of keeping you insulated and comfortable on the coldest rides of the year. Crafted with our lustrous seamless construction and non-restrictive fit, this lightweight cycling base layer epitomizes our dedication to outfitting your entire cycling wardrobe for year-round riding. Bypassing the conventional approach, this race-tuned riding base layer is spun on circular machines to increase comfort and elevate its performance. With a meticulously constructed blend of yarns and strategic body compression, this lightweight base layer has been engineered by our in-house fabric specialists and put through the wringer by our internal test teams so that it is able to react to your intensity of sweating and the subsequent cooling effect whatever the outside temperature. These are the sorts of performance gains that confirm why we state our cycling apparel is Equipment, Not Clothing."
