Pearl Izumi's innovative fabric technology, advanced design and top-of-the-line construction acknowledge the needs of pro-level cyclists. And their P.R.O. In-R-Cool bike shorts are no exception. By incorporating In-R-Cool technology with their Transfer Mineral fabrics, Pearl created shorts which reduce surface temperature by up to 35 under direct sunlight AND dry 50% faster than performance polyester. Anatomically sculpted, P.R.O. Seamless 4D chamois follows the pedaling motion for long ride comfort, reflective details enhance visibility in low light, and wide leg openings with silicone won't ride-up when you're going all out.
