Castelli Free AR 4.1 FZ Short Sleeve Jersey

The Castelli Free AR 4.1 FZ short sleeve jersey is an out and out race jersey designed to help you to perform to the highest level. Developed and directly evolved from Castelli’s pro racing jersey from four years ago the Free AR 4.1 FZ brilliantly combines a mix of classic good looks with cutting edge technical materials and construction techniques to create a fast jersey with an aero fit along with user-friendly features including a zippered rear pocket and a protective flap at the collar to prevent the full-length zip from irritating your neck. Castelli’s Velocity dimpled fabric features on the front and shoulders to bring improved wicking and faster drying and completing this ultra-modern classically styled race jersey which is available in a choice of colours.



  • Velocity dimpled fabric on front and shoulders
  • 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
  • Saves approximately 12 watts at 40 km/h compared to a normal race-fit jersey
Super!! Nice racy fit. 175cm/90kg muscular build, XL fits perfectly.
Love this jersey. Sizing is not as small as typical of Castelli so I probably didn't need to go a size up.
Great jersey, tight fit for aero, very cool with moisture being wicked instantly as the bike is moving, nice zipper pocket for ID and cash
As much as I love Castelli bibshorts, I have, until now, despised Castelli jerseys. Not only has the fit been unpredictable, but the jerseys had been constructed in such fashion that a smartphone would cause a terrible sag in the back pockets. The Free AR 4.1 FZ changes my perception. While it is still necessary to size up, the belly of the jersey is proportional to the chest so that it is neither too tight nor loose (I am 178 cm and 70 kg with a 101 cm chest and 78.7 cm waist). Very importantly, a smartphone, a couple gels, and a CO2 inflator do NOT result in the sag I had associated with Castelli jerseys. This is not a terrible fitting club jersey, nor a too tight race jersey. Really terrific.
