When every watt counts, the Pearl Izumi PI Red Bib Short gives you an extra edge. Strategic compression from Italian knit fabric supports working muscles and boosts blood flow, helping you maintain power output deeper into hard efforts. Advanced cooling technology reflects infrared heat away from your body while blocking UV rays, so you stay fresher when the sun beats down or the interval gets brutal. The ELITE 3D Levitate chamois adapts to your position with dual-density foam that cushions sit bones without restricting movement, while seamless construction and breathable mesh panels create a weightless feeling for all-day comfort.
