The Castelli Premio EVO Bibshort is built to be your ultimate long-distance companion, engineered with premium materials and extensive research to deliver unmatched comfort, support, and performance. At its core is the Progetto X2 Air Seamless seat pad, which uses a dual-layer construction: a Skin Care Layer that minimizes friction against the skin, and a Cushioning Layer with multi-density foam and breathable gel inserts placed under the sit bones and perineum for targeted pressure relief. The shorts are constructed with only three panels and use a specially developed gradient-stretch woven fabric that adapts to different parts of the body—offering increased compression in the pelvic area for pad stability, lighter stretch in the thighs for breathability, and raw-cut leg endings with integrated rubberized yarns for a secure, smooth fit.

Comfort continues through the bib strap system, featuring soft, stretchy elastic straps articulated to spread pressure evenly across the shoulders. A perforated back panel enhances breathability, while bonded edges eliminate bulk. The straps taper as they reach the shorts, increasing airflow and reducing fabric across the chest. The woven fabric is 30% lighter than comparable knits, and its sleek finish includes subtle logos for a clean, modern aesthetic. Weighing 310g and ideal for temperatures from 16°C to 35°C (60°F to 95°F), the Premio EVO sets a new benchmark in performance bibshorts.
