The Castelli Premio EVO W Short is innovatively engineered for ultimate long-distance comfort, speed, and durability. At the heart of its performance is the Progetto X2 Air Seamless Donna seat pad, featuring a two-layer construction designed for all-day rides. The Skin Care Layer sits next to the body to eliminate chafing, while the Cushioning Layer underneath uses dual-density foam and breathable perforated gel inserts to relieve pressure under the sit bones and perineum. The short’s minimalist three-panel design reduces seams for enhanced comfort, while a newly developed gradient-stretch woven fabric adapts to the body’s needs—offering light, breathable stretch in the thighs and increased compression in the pelvis to keep everything in place.

Attention to detail continues with raw-cut leg endings that use rubberized yarns for a secure, low-profile grip—eliminating the need for additional silicone. A flat waistband holds the short comfortably in place without digging in, and the woven fabric is 30% lighter than comparable knits, offering both performance and breathability. The rear panel uses a denser weave to prevent transparency, while subtle logo placement adds a refined, modern look. Weighing 270g and designed for temperatures between 16°C and 35°C (60°F to 95°F), the Premio EVO W Short is built for your biggest days on the bike.
