Castelli Premio Evo Bibshort Long Miles Just Got Easier For riders who spend serious time in the saddle, the seat pad is the whole conversation. The Premio Evo Bibshort centers its build on the Progetto X2 Air Seamless pad, a two-component system with a skin-contact layer dedicated entirely to preventing abrasion and a separate cushioning layer underneath with dual-density foam and perforated gel inserts at the pressure points. The short itself uses a gradient-stretch woven fabric that changes properties from zone to zone: lighter through the thigh for pedaling freedom, firmer through the pelvis to hold the pad in place. The bib straps are articulated over the shoulder and perforated at the back so they sit flat and breathe without cutting in. A raw-cut leg ending with rubberized yarns keeps the hem in place with no silicone gripper band to bunch or roll. Features Progetto X2 Air Seamless seat pad two-component construction with a dedicated Skin Care Layer and a separate Cushioning Layer featuring dual-density foam and perforated gel inserts at the ischia bones and perineum Gradient-stretch woven fabric varies compression and support from thigh to pelvis for zone-specific fit, and weighs 30% less than comparable knit fabric Three-panel construction with reduced seams minimizes contact points and pressure on long rides Perforated back bib panel with articulated, bonded-edge straps keeps the bib flat on the shoulder and promotes airflow without the bulk of a stitched edge Raw-cut leg ending with integrated rubberized gripper yarns holds the leg in place with no added silicone band | Castelli | Premio Evo Bibshort Men's | Size Large In Black | Rubber
