The Premio Bibshort has been designed to be your favorite bibshort ever. That's a big claim, but there's a lot of research and development to back it up.
The seat pad is central to the Premio's exceptional comfort. Castelli's top-of-the-line Progetto X2 Air Seamless pad is actually two separate components: a soft, stretchy Skin Care Layer, which has the sole purpose of preventing any rubbing on your skin, and, under that, the Cushioning Layer, which features two separate densities of foam along with breathable perforated gel inserts under the ischia bones and perineum. Added comfort continues through the construction of the short with reduced seams and only 3 panels.
Castelli engineered a new fabric that changes depending on the contours of the body. The lower leg has a raw-cut leg ending and rubberized yarns that keep the short leg in place. The fabric becomes lighter in the thigh, while the four-way stretch provides just the right amount of muscle support. In the pelvis area, compression and support increase to keep the seat pad and everything else in place. At the back, there's a thicker fabric to avoid any transparency issues.
The premium fabrics extend to the bib straps. The perforated back keeps you cool and the edge is bonded so you don't feel the thickness of a stitched edge. The elastic straps have just enough modulus (return) to hold your shorts securely in place without cutting into your shoulders. Castelli carried the less-is-more theme into this design, with minimalist laser-etched logos and subtle finishing. It looks as premium as it feels. You can tell that every component, every stitch, every detail has been obsessed over. You'll not find a better bibshort.
