Castelli Sidi Cielo Aero Race 4.0 Cycling Short Sleeve Jersey
The Castelli Sidi Aero Race Jersey is a significant leap forward in aerodynamics and weight, but weve kept this model in the line because its one of the most comfortable all-around jerseys weve ever made. And its still one of the most aero jerseys out there. Perfect fit and excellent moisture management with a nice fresh graphic. 
 
Features:
  • Saves approximately 12 watts at 40km/h compared to a standard cycling jersey, and a full 12 watts faster than the industry-leading model
  • Velocity Dry fabric on front and shoulders for improved wicking and faster drying
  • Zipp YKK Vislon
  • Nervato fabric at arm holes for improved aerodynamics
  • Silicone gripper elastic at waist
  • GIRO3 arm elastic for flat, aero fit
  • Three rear pockets
  • Castelli Jersey with Sidi's Logo
