Staying cool is essential when you're pedaling near the redline, and POC's Raceday Climber Jersey is designed specifically to breathe, wick moisture, and keep you from overheating on the toughest climbs and hottest days. Built from ultralight polyester, the Raceday almost instantly transports moisture from your skin to the surface of the jersey, where it evaporates quickly to keep you cool and dry. Mesh inserts under the arms provide extra ventilation and mobility for aggressive pedaling and hands off the bars victory celebrations, and the Coolmax polyester and elastane cuffs and hem provide a snug fit for increased aerodynamic efficiency. POC didn't skip out on features to make the Raceday fast, either it boasts triple back pockets for bottles, gels, and phones, a full length zipper for customizable ventilation, and a soft collar lining to keep your chin from chafing. The jersey is finished with reflective details on the collar, sleeve, and back, to take some of the worry out of dawn and dusk rides.
