Sure, bib shorts can be a clean and simple piece of your kit -- but why stop there' We suspect that designers at Castelli have been asking the same question, which may explain their meticulous engineering of the Tabula Rasa Bib Shorts. The Tabula Rasa Shorts are built with very little compromise, both in the creative department and the performance side of things, which becomes immediately apparent with their ProFit LYCRA fabric that offers maximum flexibility, while allowing graphic designs to be printed throughout. ProFit Lycra has a knack for hugging your muscles gently, while wicking away perspiration to keep you comfortable and dry. The inner thigh features panels of durable nylon to hold up to your saddle on long rides, while the inside features Castelli's KISS Air2 Donna chamois to cushion you. The KISS Air2 Donna uses dual-density foams to absorb harsh vibrations from the road, with infinitely variable thickness that tapers thicker support where you need it most, and thinner where you don't. It's topped off with a stretchy, soft microfiber layer that provides total freedom of movement without irritation.
