Assos' Mille line is tuned in for complete comfort on every ride, and the Mille GT Winter Bib Tight GTO C2 is specially designed with that thoughtfulness for winter riding. This bib tight is engineered with highly flexible insulation and Assos' signature Mille insert to make for optimal support in challenging wintery weather conditions. We like that this bib tight is form-fitting and flexible without being restrictive and that it's designed to battle the toughest elements on our ride.
