Q36.5 Gregarius Winter Bib Tights Women - Black One reason you feel slower in winter is that your leg muscles don't warm up enough. With the Q36.5 Gregarius Winter Bib Tights, you can say goodbye to cold legs and set new personal bests even in the coldest temperatures. The Gregarius Winter Bib Tights have been improved with our proprietary UF Thermo Plus fabric. This innovative material is extremely tightly knitted and performs much more efficiently than conventional nylon winter tights. The outer layer is made of nylon with a DWR finish, protecting your legs and back from rainwater and road grime. The inner layer is made of a special hydrophobic polyester thread that insulates while wicking moisture away from your skin. Like all Q36.5 bib tights and tights, the Gregarius Winter Bib Tights for women are tailored to the body and pre-shaped for your cycling position. The result is no excess material behind the knees bunching up and irritating you while riding, for example. Minimal seams and strategically placed panels ensure you can move freely without feeling constricted or tight around the knees while pedaling. Features of the Q36.5 Gregarius Women's Winter Bib Tights
