We’Ve Taken Our Favorite Aero Race 4.1 Jersey And Made It Richer By Producing It In Dyed Fabrics Rather Than The Usual Sublimation Printed Fabrics. This Gives Deeper, More Saturated Colors While Avoiding The Shiny Look That Inevitably Comes From The High Heat And Pressure Of Sublimation Printing. You Still Get The Great Fit, Great Comfort, Great Moisture Management And Great Aero Performance From The Race Background Of This Jersey. Look Smart; Go Fast.

  • Full-Length Ykk® Vislon® Zipper With Neck Protector
  • Nervato Fabric At Armholes For Improved Aerodynamics
  • Silicone Gripper Elastic At Waist
  • Mesh Raw-Edge Arm Grippers
  • Zippered Rear Pocket
  • Reflective Heat-Transfer Viz Strips
