Zero inseam construction shifts the comfort equation on long, hot days — no fabric, no seam, no friction against the thigh — and that's the headline detail on Pearl Izumi's PI/Red Bib Shorts. Built from an ultra-light nylon fabric that delivers targeted compression to promote circulation and reduce fatigue through long, hot efforts, the bibs add In-R-Cool infrared technology with coldblack to reduce heat absorption from sunlight while providing UV protection. This is the flagship road bib at the top of the PI/Red collection, and it's where Pearl Izumi puts every chamois, fabric, and construction trick they've developed.

Inside, the dual-density ELITE Levitate 3D chamois minimizes skin abrasion and sit-bone discomfort while maintaining flexibility for sustained comfort in the saddle.

Italian lightweight mesh through the back panel and bib upper maximizes airflow, and the raw-edge leg bands with silicone grippers keep everything securely in place without pinching. Raw-edge hems are the detail that separates race-level bibs from training bibs — no elastic band digging into your quad, no compression line showing through skin, just a clean edge that holds where it's supposed to....
