Castelli Giro108 Race 8S Jersey

The Giro108 Race 8S Jersey is the same aero jersey used by the pros in the Italian Grand Tour, refined in the wind tunnel to deliver up to 6% CdA savings. Available in shades to match each of the Giro's distinctive leader jerseys, it gives you an edge over the competition.

Designed using CFD-based fabric placement and seam construction and tested in the wind tunnel and on real roads, this jersey, with its world map graphic celebrating the Giro's worldwide popularity, helps you to go faster with less effort, with the ribbed fabric of the shoulders helping to detach the airflow and shave watts.

Speed doesn't come at the cost of comfort, though, with bonded sleeve endings feeling soft against your skin, lightweight fabric allowing optimal cooling and elastic at the waist anchoring the hem and supporting the three rear pockets, even when they're loaded with gels, tools and emergency layers. Wear it to cheer on your heroes while emulating their impressive velocity.
