Ergonomic and performance-driven: these PR-S 2.0 bib shorts combine proven, reliable technical materials with new, streamlined cuts for a completely refreshed look. The turning point is the innovative X Air Bib strap construction, designed to drastically reduce the layers of fabric in contact with the skin and leave the back free to breathe. The result is stability and an unmatched feeling of lightness and freshness. The anatomical side panel, made from calendered fabric with a multi-sphere pattern, helps reduce drag and improve on-bike aerodynamics. The Leg Comfort System is a wedge-shaped elastic fabric insert placed at the leg hem, allowing the shorts to adapt to different muscle shapes. The chamois is applied with a Tri-Stitch seam that improves elasticity and resists tearing with use. Finally, reflective details at the hem ensure visibility in tunnels and in the evening hours.
