Castelli Free AR 4.1 FZ Short Sleeve Cycling Jersey - SS19
This jersey is an evolution of Castelli's top pro racing jersey from just a couple of year's back. It's also Castelli's first aero race jersey that didn’t get retired when the next generation of faster, more aero jerseys came along. The 4.1 jersey takes a different direction, away from pro racing. This updated jersey gets a zippered rear pocket, a flap behind the zipper to protect your neck, updated Velocity dimpled fabric on the front and an angled pocket for easier access. This makes it the one ideal jersey for all your rides, whether you’re sprinting for the win or trying to survive the Sunday group ride.
  • Saves approximately 12 watts at 40 km/h compared to a normal race-fit jersey
  • Velocity dimpled fabric on front and shoulders for improved wicking and faster drying
  • 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
  • Weight:123g
