The Castelli Premio Black Bib Short makes long distance riding more comfortable thanks to years of perfecting the long-distance bib short. The Premio can be used for casual endurance rides and fast long-distance races. They are also protective in cool fall and hot summer weather. Fit has been perfected using fabrics that compress without excessive tightness. Gradient stretch has been woven through the wicking material that keeps a rider dry. The Premio fits perfectly while the soft, lightweight material is wonderfully comfortable. Weighing 30% less than the traditional woven fabric, the Premio feels great on climbs. The bibs lie flat and are perforated so they won’t get clammy against skin. Integrated gripper elastic at leg ending is designed to keep the shorts from riding up a leg with minimal silicone grippers which maximizes the comfort needed to make long distance riding more enjoyable. The Progetto X² Air Seamless seat pad is Castelli’s long distance chamois pad. A new seamless skin-care layer is softer against skin and it reduces abrasion. The cushioning layer is separate so air can flow between the two layers keeping a seat dry. Padding is thicker under the seat bones where a rider needs the most cushioning. It thins down on the sides so excessive bulk is avoided. Under the sensitive ishial and perineum pressure areas, perforated viscous padding has been added for the extra needed protection. The Castelli Premio Black Bib Short is Castelli’s best bib shorts for riders who pack long distance rides into their training schedule and thrive off ultra-distance races.
