Castelli Men's Free AR 4.1 Jersey

Based on the 4th iteration of Castelli's podium worthy Aero Race jersey, this version represents a race-inspired jersey with more creature comforts than its watt chasing protégé. By incorporating 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, the Free Aero Race 4.1 has become the ideal all-rounder. While casual enough for the group ride, this jersey is equipped with the technology to dial in a pace that'll turn the ride inside out.

Note: Castelli apparel is designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.
