The Pearl Izumi PI Red Jersey is built for your hottest training days, featuring Italian compression fabric that boosts circulation and maintains an aerodynamic profile through tempo efforts and long climbs. Cooling fabric panels activate when you start sweating, while UPF protection and anti-odor treatment keep you shielded and fresh through brutal intervals. With a race-tuned fit, three rear pockets with internal divider, and reflective elements visible up to 100 meters, this jersey is engineered to perform at full gas from the first pedal stroke to the final sprint.
